1. A static eliminating device comprising a substrate provided with a light emitter and a limiting resistor, the light emitter being arranged at an opposing position of a surface of a photosensitive body and irradiating static eliminating light for eliminating the surface of the photosensitive body, the limiting resistor for the light emitter being provided on a same surface as the light emitter,
wherein one end of the light emitter is connected to a power source via the limiting resistor,
the static eliminating device further comprising:
a first switching section provided at a position from the limiting resistor and the light emitter, which are connected in series, to the power source, the first switching section connecting the power source to the limiting resistor and the light emitter at an ON state, and disconnecting the power source from the limiting resistor and the light emitter at an OFF state;
a second switching section provided at a position from the limiting resistor to the power source, which are connected in series, the second switching section connecting the power source to the limiting resistor at the ON state, and disconnecting the power source from the limiting resistor at the OFF state; and
a controller controlling ON/OFF operations of the first and the second switching sections,
wherein the light emitter is branched from a position between the limiting resistor and the power source connected in series, and is serially connected to the limiting resistor,
the first switching section is provided at a position from the light emitter and the power source,
when driving the light emitter, the controller switches the first switching section to the ON state and switches the second switching section to the OFF state, and
when heating the surface of the photosensitive body, the controller switches the first switching section to the OFF state and switches the second switching section to the ON state.
