Estimating the term…
An electrophotographic image forming apparatus for forming an image on a recording medium includes: a container mounting portion for attachable/detachably mounting a developer replenishing container having a developer containing portion containing a developer and a discharge port for discharging a developer contained in the developer containing portion, a cartridge mounting portion for attachable/detachably mounting a cartridge having a developing device for developing an electrostatic latent image formed on an electrophotographic photosensitive member using a developer, a developer containing portion for containing the developer used in developing with the developing device, and a developer receiving port for receiving a developer from the developer replenishing container to the developer containing portion, wherein the discharge port in the developer replenishing container and the developer receiving port in the cartridge are communicatively connected to each other in a state where the developer replenishing container and the cartridge are mounted within the electrophotographic image forming apparatus body.
An electrophotographic image forming apparatus for forming an image on a recording medium comprising:
An electrophotographic image forming apparatus in which a plurality of cartridges and developer replenishing containers are attachably and detachably positioned, wherein each of said developer replenishing containers has a developer containing portion for containing a developer, a discharge port for discharging a developer contained in said developer containing portion to a developer containing portion of a corresponding one of said cartridges, and a replenishing container opening and closing member for openably sealing said discharge port, and in a state where said cartridges are mounted to a main body of said electrophotographic image forming apparatus, the replenishing container opening and closing members of said plurality of developer replenishing containers can be simultaneously moved from respective sealed positions of said discharge ports to respective opened positions.
An electrophotographic image forming apparatus in which a plurality of cartridges and developer replenishing containers are attachably and detachably positioned, wherein each of said cartridges has developing means for developing an electrostatic latent image formed on an electrophotographic photosensitive member using a developer, a developer containing portion for containing the developer used in developing with said developing means, a developer receiving port for receiving the developer contained in a corresponding one of said developer replenishing containers into said developer containing portion, and a cartridge opening and closing member for openably sealing said developer receiving port, and in a state where said cartridges are mounted to a main body of said electrophotographic image forming apparatus, the cartridge opening and closing members of said plurality of cartridges can be simultaneously moved from respective sealed positions of said developer receiving ports to respective opened positions.
