ABSTRACT:
A process cartridge detachably mountable to a main assembly of an electrophotographic image forming apparatus includes an electrophotographic photosensitive member; a cartridge coupling member, provided coaxially with the photosensitive member, for engaging with a main assembly coupling member to receive driving force for rotating the photosensitive member when the process cartridge is mounted to the main assembly; a developing roller for supplying toner to the photosensitive member to develop a latent image formed on the photosensitive member; a driving force transmission member, disposed at one longitudinal end of the photosensitive member to transmit the driving force from the photosensitive member to the developing roller; a driving force receiving member, engaged with the driving force transmission member and disposed at one longitudinal end of the developing roller, for receiving the driving force for rotating the developing roller; and a magnetic seal member, disposed with a gap from the developing roller, for preventing leakage of the toner in a longitudinal direction of the developing roller.
