PROBLEM TO BE SOLVED: To prevent, in an electrophotographic device equipped with a process cartridge, toner scatter at the time of the detachment of the process cartridge from the main body of the electrophotographic device without an increase in cost due to the provision of an extra member such as a sealing member. SOLUTION: The electrophotographic device is equipped with a process cartridge 10 which is composed of at least a developing device 14 and free to be attached/detached to the main body of the electrophotographic device. The device is also equipped with a toner replenishment device 30 for replenishing the developing device 14 with toner through the toner receiving port 48 of it, and a shutter member 55 for opening/closing the toner receiving port 48 from inside the cartridge case 11 of the process cartridge 10. When the process cartridge 10 is attached to the main body of the device, the toner supply port 47 of the toner replenishment device 30 is brought close to the toner receiving port 48, and when it is detached from the main body of the device, the toner receiving port 48 is closed by the shutter member 55 from inside the cartridge case 11. |
