Process cartridge, electrophotographic image forming apparatus and connection method of connecting contacts

摘要

A process cartridge (B) detachably mountable to a main assembly of an electrophotographic image forming apparatus includes an electrophotographic photosensitive drum (1); process means actable on the electrophotographic photosensitive drum; a memory element for storing information relating to the process cartridge; a connector (71) including a plurality of connecting contacts, arranged along a line substantially perpendicular to a longitudinal direction of the electrophotographic photosensitive drum, for electrical connection with the main assembly to transmit to the main assembly information stored in the memory element when the process cartridge is mounted to the main assembly, wherein a connecting contacts of the plurality of connecting contacts which is closest to the electrophotographic photosensitive drum is a contact for electrically grounding a substrate of the memory element.
