Abstract
A process cartridge and a unit include a cover member, a memory element provided on the cover member, and a unit abutting portion. The process cartridge and the unit can be detachably mounted to the main body of an electrophotographic image forming apparatus. The main body of the electrophotographic image forming apparatus includes a main body base member and a communication device. The process cartridge and the unit are positioned to a predetermined location by the unit abutting portion abutting against the main body base member, when the process cartridge and the unit are mounted to the main body of the electrophotographic image forming apparatus. In this state, the storage element is disposed at a position facing the communication device and can communicate with it in a noncontacting manner.
