Abstract:
1. An electrophotographic image forming apparatus for forming an image on a recording material, comprising: a transfer member for transferring a developed image formed on an electrophotographic photosensitive drum onto the recording material; an image forming unit including the electrophotographic photosensitive drum and a cartridge mounting portion for demountably mounting a cartridge accommodating a developer; a cleaning member for removing the developer remaining on a surface of said electrophotographic photosensitive drum; a residual developer container, demountably mounted to said image forming unit, for accommodating the developer removed by said cleaning member; wherein said image forming unit is movable, relative to a main assembly of the apparatus in a state that said cartridge and residual developer container are mounted to said image forming unit, between 1) an image forming position when said cartridge is positioned to be capable of forming the image, in which said developer container and said residual developer container are prevented from being removed from an inside to an outside of the main assembly of the apparatus, and 2) a mounting and demounting position in which said residual developer container and said cartridge are detachably mountable individually relative to said image forming unit, and are permitted to be moved from the inside to the outside of the main assembly of the apparatus.
