摘要：An image forming apparatus includes a movable image bearing member (1),having a photosensitive layer (1a); a charging member (2) for charging the image bearingmember (1), a light radiating device (10) for radiating light on the image bearing member(1); a detector for detecting a datum relating to the thickness of the photosensitive layer(1b) on the basis of the voltage-current characteristic between the charging member (2)and the image bearing member (1); and a controller for controlling the amount of lightradiated from the light radiating device (10) so that the amount is increased withdecrease of the thickness of the photosensitive layer (1b); the surface potential of theimage bearing member (1) is also controlled on the basis of this voltage-currentcharacteristic.
