An electrophotographic image forming apparatus detachably mounts plural process cartridges. Each cartridge includes an electrophotographic photosensitive drum, a developing roller, a drum frame and a roller frames movable between a contact position where the roller contacts the drum and a spacing position where the roller is spaced from the drum. The apparatus includes a drawing member detachably mounting the cartridges and movable substantially horizontally crossing an axial direction of the drums between a mount position where the cartridges are mounted in a main assembly of the apparatus and a drawn position drawn out of the main assembly, a spacer movable between a retracted position where the drawing member is retracted from a movement path of the cartridges to permit movement of the mounted cartridges and an operating position where the drawing member is in the movement path to move the drum frames between the contact and spacing positions. |
