ABSTRACT:
An image forming apparatus includes a movable image bearing member, having a photosensitive layer; an image forming device for forming an image on the image bearing member: a charging member for charging the image bearing member; and a light radiating device for radiating light on the image bearing member; a detector for detecting a datum rotating to a thickness of the photosensitive layer on the basis of the voltage-current characteristic between the charging member and image bearing member; and a controller for controlling the amount of light radiated from the light radiating device to be increased with decrease in the thickness of the photosensitive layer, in response to the detector.
