Title:
ELECTROPHOTOGRAPHIC DEVICE
Document Type and Number:
Japanese Patent JP3234389
Kind Code:
B2
Abstract:
PURPOSE: To improve maintainability by decreasing frequency in toner cartridge replacement, in an electrophotographic device provided with a toner-recycling mechanism.
CONSTITUTION: Not only the toner cartridge 7a is set in a developing device 3 but also the toner cartridge 7b is set in a cleaner 5, and toner set in the cleaner 5 is carried to the developing device by means of a toner-carrying mechanism. Thus, an amount of toner which is supplied for development is increased. Also, both the toner cartridges 7a and 7b are integrated. Therefore, the frequency in toner cartridge replacement decreases, and maintainability improves by replacing the toner cartridge 7 when the toners in both the toner cartridges 7a and 7b are used up, thereby completing the cartridge replacement only at one time.
