ABSTRACT:
A process cartridge detachably mountable to a main assembly of an electrophotographic image forming apparatus, includes a photosensitive drum; a developing roller rotatable in the drum-rotating direction when the cartridge is mounted to the apparatus; first and second separation members disposed at one and the other end of the roller so as to provide a gap between the roller and the drum and contacting the drum surface adjacent one and the other end thereof; a charging roller, contacting and charging the drum, which is rotatable with a peripheral speed difference relative to the drum; and a cleaning member contacting the drum adjacent one end thereof, the cleaning member having an effective area outside a developing-roller developing zone and inside a charging-roller-and drum contact region and which is in a region where the first separation member contacts the drum.
