Abstract

A color electrophotographic image forming apparatus is usable with process cartridges that each include an electrophotographic photosensitive drum. The image forming apparatus includes a movable member that is movable between an inside of the main assembly of the apparatus and an outside of the main assembly of the apparatus in a direction crossing with a longitudinal direction of the drum while carrying the cartridges. A main assembly electrical contact is provided inside the main assembly along a movement path of the movable member. An intermediary electrical contact is provided and includes a first electrical contact portion that is disposed inside the movable member, with the intermediary electrical contact being electrically connectable to a cartridge electrical contact of a cartridge, and a second electrical contact portion is disposed outside the movable member, with the second electrical contact portion electrically connectable to a main assembly electrical contact provided in the main assembly.
