Abstract
A process cartridge detachably mountable to a main assembly of an electrophotographic image forming apparatus, includes a developer discharging member; a cartridge positioning portion for engagement with a main assembly positioning portion provided in the main assembly when the cartridge is mounted to the main assembly; a photosensitive member driving force receiving portion for receiving a driving force for rotating the photosensitive member from the main assembly when the cartridge is mounted to the main assembly; and a discharging member driving force receiving portion for receiving a driving force for rotating the developer discharging member from the main assembly when the cartridge is mounted to the main assembly. The rotational directions of the photosensitive member driving force receiving portion and the discharging member driving force receiving portion are the same, and the rotation directions are such that a rotation moment is produced so as to contact the cartridge positioning portion to a lower surface of the main assembly positioning portion of the apparatus.
