An electrophotographic image forming apparatus (100) to which a plurality of process cartridge (s) are detachably mountable, the cartridge (s) including an electrophotographic photosensitive drum (1), a developing roller (3a), a first frame (5) supporting the drum, and a second frame (3) supporting the developing roller which is movable between a contact position where the developing roller contacts the drum and a spacing position where the developing roller is spaced from the drum, the apparatus including a drawing member (35) to which the plurality of cartridges are detachably mountable, the drawing member being movable in a substantially horizontal direction perpendicular to an axial-direction of the drum between a mount position where the cartridges are mounted in a main assembly of the apparatus and a drawn position where the drawing member is drawn out of the main assembly; a spacer member (92) movable between a retracted position where the spacer member is retracted from a movement path of the cartridge to permit movement of the cartridge mounted on the drawing member and an operating position where the spacer member is in the movement path to move the second frame between the contact position and the spacing position. |
