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.
