Abstract
An image forming apparatus includes a rotatable photosensitive member including a conductive base and a photosensitive layer located on a surface of the base; a charging device located in the vicinity of the photosensitive member for charging the photosensitive layer; a charge removing device located upstream with respect to the charging device in a rotation direction of the photosensitive member for radiating light toward the photosensitive layer prior to charging performed by the charging device to uniformize a surface potential of the photosensitive layer; a light radiation device for radiating light to a charging area of the photosensitive layer in the state of being charged by the charging device and for adjusting the amount of the light to be radiated; an exposing device for radiating light corresponding to an image toward the photosensitive layer in the state of being charged; a developing device located downstream with respect to the exposing device in the rotation direction of the photosensitive member; a change detection device for detecting a change in at least one of a charging potential of the photosensitive layer and a sensitivity of the photosensitive layer; and a co…
