Abstract
An electrophotographic image forming apparatus includes a main assembly mounting a process cartridge, a movable member movable from outside to inside the main assembly while supporting the cartridge, and an intermediary electrical contact supplying a bias voltage to the cartridge and disposed at a downstream side of the movable member. The cartridge includes an electrophotographic photosensitive drum, process means actable on the drum, an input electrical contact at a leading end with respect to the moving direction of the movable member when the cartridge is supported on the movable member and contacting the intermediary electrical contact when the cartridge is supported on the movable member, a contact portion provided at an upstream side with respect to the moving direction and contactable to the movable member when the input electrical contact is contacted by the intermediary electrical contact and is elastically urged by the intermediary electrical contact.
