| 1. A transfer belt unit mounting/dismounting device that mounts and dismounts a transfer belt unit to and from an image forming
apparatus, comprising:
a guide section that is provided in a predetermined mounting position of the image forming apparatus to guide a transfer belt
unit inserted in a predetermined direction by a guide surface, the guide surface having first positioning sections thereon
that are formed to position the transfer belt unit located in a predetermined position on the guide surface with respect to
the image forming apparatus;
a moving mechanism that moves the guide section between a first position for guiding the insertion of the transfer belt unit
in the predetermined direction by the guide surface and a second position for positioning the transfer belt unit by the first
positioning sections; and
second positioning sections that cooperate with the first positioning sections in the guide section moved to the second position
by the moving mechanism to position the transfer belt unit with respect to the image forming apparatus, wherein
each of the first positioning sections is a convex that is formed in the predetermined position of the guide surface and positions
the transfer belt unit with respect to the image forming apparatus by supporting a protrusion provided in the transfer belt
unit cooperating with each of the second positioning sections.
