Abstract:
1. A process cartridge detachably mountable to a main assembly of an electrophotographic image forming apparatus having a transferring roller and main assembly communication means, said process cartridge comprising: an electrophotographic photosensitive drum; cleaning means, contacting said electrophotographic photosensitive drum, for removing developer remaining on said electrophotographic photosensitive drum; a developer accommodating portion configured to accommodate the developer removed from said electrophotographic photosensitive drum by said cleaning means; a developing roller configured and positioned to develop an electrostatic latent image formed on said electrophotographic photosensitive drum with the developer; and storing means, including an information storing portion configured to store predetermined information and cartridge communicating means for effecting wireless communication of the predetermined information stored in said information storing portion with the main assembly communication means, wherein said storing means is disposed inside said developer accommodating portion, and said storing means is disposed at a leading side with respect to a direction in which in said process cartridge is mounted to the main assembly of the apparatus; wherein said electrophotographic photosensitive drum contacts along the length thereof the transferring roller for receiving a bias voltage to transfer a developed image provided by said developing roller onto a recording material; and wherein said storing means is disposed at the same side of said process cartridge as said electrophotographic photosensitive drum with respect to a tangent line passing through a contact point between said electrophotographic photosensitive drum and the transferring roller extending in a direction crossing the longitudinal direction of said electrophotographic photosensitive drum.
