Patent ID: 8509650

Claim:
An electrophotographic image forming apparatus for forming an image on a recording material, comprising: a cartridge for storing developer; an intermediary transfer member, opposed to an eletrophotographic photosensitive drum, said electrophotographic photosensitive drum transferring a developed image formed on said electrophoto graphic drum onto said intermediate transfer member; a transfer member for transferring a developed image borne on said intermediary transfer member onto the recording material; a supporting member movable, while supporting a cartridge, between an image forming position for effecting image formation and a mounting and demounting position, away from the image forming position, for mounting and demounting said cartridge to said mounting portion; a residual developer container, mounted to said supporting member and provided with a cleaning member for removing developer remaining on a surface of said intermediary transfer member, for accommodating the developer removed by said cleaning member; wherein said residual developer container is detachably mountable relative to said supporting member when said supporting member is in the mounting and demounting position, and wherein said residual developer container is disposed such that in a state that said supporting member is in the image forming position, said cleaning member acts on the surface of said intermediary transfer member at a position downstream of said transfer member and upstream of said electrophotographic photosensitive drum with respect to a movement direction of said intermediary transfer member.
