DEVELOPER SUPPLY CONTAINER REMOVABLY MOUNTED AT MAIN ASSEMBLY BODY OF ELECTROPHOTOGRAPHIC IMAGE FORMING APPARATUS, AND ELECTROPHOTOGRAPHIC IMAGE FORMING APPARATUS

摘要

PURPOSE: A developer supply container and an electrophotographic image forming apparatus are provided to accurately position a developer supply container at a main assembly body of an electrophotographic image forming apparatus. CONSTITUTION: A developer storing part(12k) stores a developer. A developer supply opening supplies the developer of the developer storing part to a process cartridge(10). A container closing member is movable between a closing position of closing the developer supply opening and an opening position retracted from the closing position. A first container guide member(12g1) is formed at one wall of a developer supply container crossing vertical direction of the developer supply container, and is guided by a main assembly body guiding part. A second container guide member is formed at the other wall crossing vertical direction of the developer supply container, and is guided by the main assembly body guiding part. A container force receiving part is combined with a cartridge combining part formed at a cartridge for receiving force for opening the developer supply opening. A first container position setting part(12r2) is combinable with a first main assembly body position setting part. The first container position setting part is positioned by the first main assembly body position setting part. The developer supply container is positioned by first and second container guide parts supported by the main assembly body guide part at an end corner.
