Abstract
A color electrophotographic image forming apparatus is usable with process cartridges detachably mountable to the apparatus. The cartridges include an electrophotographic photosensitive drum. The apparatus includes: a movable member movable between the inside and outside of the apparatus while carrying the cartridges; a first electrical contact inside the apparatus along a movement path of the movable member; and a second electrical contact including a first portion inside the movable member and connectable to a cartridge electrical contact and a second portion outside the movable member and connectable to an electrical contact provided in the apparatus. A space is provided between the movable member and the first contact to prevent the movable member from contacting the first electrical contact when moving from outside to inside. The second portion is connected to the first electrical contact when the movable member is lowered after moving linearly from the outside to the inside.
