Class 399
ELECTROPHOTOGRAPHY
Class Definition:
This class provides for electrophotographically reproducing
an original (e.g., document) by the action of light directly
from the original to a photoconductive member whose
electrical conductivity, electrical charge, magnetic
condition, or electrical emissivity of a photoconductive
medium is selectively altered by the action of light to
produce an electrostatic latent image which persists after
imaging based upon differences in such electrical property.
The latent image is made visible by development; and the
developed image may be made permanent by transfer and fixing,
or fixing. This class provides for the subcombinations
directed to charging, developing, transferring, fixing,
cleaning, or sheet feeding for an electrophotographic
apparatus whether or not the imaging light is directly from
the original. This class also provides for methods and means
for perfecting the apparatus provided above (e.g., control of
electrophotographic process, diagnostics, operator interface,
etc.).
(1) Note. The apparatus herein classified generally
involves the application of a uniform electrostatic charge to
a photoresponsive medium comprising a conductive support
coated with a photoconductive insulator. Latent electrostatic
images are formed by exposure of an original directly onto
the photoresponsive medium through an optical lens system.
The charge applied to the light sensitive medium is
selectively discharged by exposure and remains only on
selected portions of the photoresponsive medium (i.e., those
areas which correspond to the original image). The
photoresponsive medium is moved to a developing station where
toner is applied to the charged areas of the photoresponsive
medium forming a visible image thereupon. The photoresponsive
medium is then moved to a transfer station where the toned
image is transferred to a copy substrate (e.g., a piece of
paper). The toned substrate is then fed to a fixing station
where the toner is permanently affixed to the paper, usually
by heat or pressure. The photoresponsive medium is then moved
to a cleaning station where untransferred toner and any
leftover electrical charge are removed so another copy cycle
can begin.
(2) Note. The use of the limitation "directly" above
excludes image formation systems in which an image of an
original is detected and converted to electrical signals
which are subsequently utilized to generate further
illumination signals to optically form an image of the
original on the medium. This excluded subject matter may be
found, for example, in Class 347, subclasses 112+, and in
Class 358, subclasses 400+ and more specifically 401.
However, the nominal recitation of a light image to an
electrical signal or an equivalent statement would not serve
to exclude subject matter from Class 399. Also,
Electrophotography has no modification of converted
electrical signals.
OTHER CLASSIFICATION SYSTEMS
Each subclass definition may contain an OTHER CLASSIFICATION
SYSTEMS listing that is to be used for informational purposes
only. These classification listings may change at any time
after their publication and are therefore not guaranteed to
be current. In addition, the classification listing does not
necessarily indicate the sole relationship between the U.S.
Patent Classification System and foreign classifications.
Even where a single classification is listed for a single
U.S. subclass, a one-to-one correlation should not be
inferred. As a result, information contained therein is
considered to be only a guide to related subject matter.
Types of other classification systems may include
IPC[supscrpt]6[end supscrpt] which indicates an International
Patent Classification (sixth edition) of the World
Intellectual Property Organization (WIPO), JPO/FI which
indicates the Japanese Patent Office and its File Index (FI
is a subdivision of the IPC with related subject matter)
classifications, or the European Patent Classification (EPC)
which indicates the European Patent Office's classification
and also further subdivides the IPC into related subject
matter.

GLOSSARY:
ELECTROSTATOGRAPHY
The formation and utilization of latent electrostatic charge
patterns for recording or reproducing patterns in viewable
form, for example: reproducing information from an original
or carrier by selectively exposing a photoconductive member
to an electrical or magnetic condition that produces a latent
image whereby the image is developed to a visible image, then
transferred and fixed from the photoconductive member to a
medium.
LIGHT SOURCE
The source of illumination for the copier. The light source
includes filters, reflectors, screens, and other light
modifiers used to affect the spectral distribution, spatial
distribution, and intensity of the illumination.
IMAGE
The representation of an object (e.g., original, carrier)
produced by the transmission or reflection of light incident
upon the original.
IMAGE-BEARING MEMBER
A substrate for holding an electrostatic charge pattern or a
toner image.
IMAGE, LATENT
The invisible image produced by the action of light alone or
with other electrostatic charge-producing means on, or in, a
photoreceptor. A latent image may be made visible by
development.
IMAGING
Forming an image that is a reproduction of an original.
MACHINE
A complete unit, in itself, for imaging an original or
carrier onto a receiver. It may also include means for
developing, transferring, and fixing the image, as well as
means for handling the record carrier on which the image is
fixed.
MASTER
(a) The negative or positive original from which
reproductions are made, (b) a microform copy used for the
production of copies, or (c) a copy from which additional
reproductions are made.
NEGATIVE
A visible image on a copy material in which the dark portions
of an original appear light and the light portions appear
dark.
ORIGINAL
Any object (generally two-dimensional) from which a copy is
made by forming an image thereof on a photoconductor.
PHOTOCONDUCTIVE MATERIAL
A material that is an insulator in the dark and conducts
electricity in proportion to the amount of impinging light or
actinic radiation. This is usually provided as a layer of
electrically conductive material on a conductive support.
During use, the electrical conductor is charged (sensitized)
in the dark, and light (in image configuration) allows or
causes the electrically conductive layer to conduct so that
the charge leaks through to the conductive layer leaving a
charge pattern corresponding to the original image
(electrostatic latent image).
PHOTOCONDUCTIVE MEMBER
A medium whose electrical conductivity, electrical charge,
magnetic condition, or electrical emissivity is selectively
altered by the action of electromagnetic radiation during
imaging.
PLATEN
A flat or curved piece of rigid material on or against which
an original is placed for imaging the original onto a
photoconductive member.
TONER
Charged material (e.g., finely divided powder; i.e., usually
thermoplastic or pigmented polymer particles), ink, or
magnetic particles used in electrostatic processes to make
visible a latent image and which may be treated (e.g., fused,
dried, etc.) to render the image permanent. Toner can be
charged by triboelectric action, by the direct application of
charge (e.g., corona), or by inducing the charge through the
action of the electrostatic latent image. The material may
include or exclude a carrier element and may also be called
"marking particles" or "developer material."

(2) Note. Rather than forming a total light image of an
original, the light image is filtered (or different colored
exposure lights are used) to produce a single-colored light
image which is a light image of the original. A succession
of latent images are thus produced, each corresponding to a
separate, different-colored, single light image. Each latent
image is developed with toner complementary in color to the
color of the filtered light image. The toner images are
superimposed in registration to produce a color copy
corresponding to the latent image formed with red light
developed with cyan toner. A blue light image is developed
with yellow toner. A green light image is developed with
magenta. Also, another term for color separation images is
color resolved images.
