Abstract
A process cartridge detachable mountable to a main assembly of an electrophotographic image forming apparatus includes an electrophotographic photosensitive drum; a developing roller for developing an electrostatic latent image formed on the photosensitive drum with developer; a transferring roller for causing transfer of the developer image from the photosensitive drum to a recording material; a cleaner, contacted to the photosensitive drum, for removing a developer remaining on the photosensitive drum; a developer accommodating portion for accommodating developer removed from the photosensitive drum by the cleaner; and a memory including a storing portion for storing predetermined information and a communicator for effecting wireless communication of the predetermined information stored in the storing portion with a main assembly side communicator provided in the main assembly of the electrophotographic image forming apparatus. The storing portion is disposed inside the developer accommodating portion and the storing portion is disposed on the same side of the process cartridge as the photosensitive drum with respect to tangent lines passing a contact point between the photosensitive drum and the developing roller or transfer roller.
