An image-forming apparatus includes a mechanism that controls the replenishment amount of toner (120) to a predetermined value. A toner cartridge (121) holds toner therein. The toner cartridge (121) is detachably attached to a process cartridge (122). The process cartridge has a toner reservoir (122b) that holds the toner supplied from the toner cartridge, a photoconductive drum (12BK), and a developing roller (24BK) that supplies the toner to the photoconductive drum. A valve (121b) is located between the toner cartridge and the process cartridge and supplies the toner from the toner cartridge to the process cartridge. When the valve rotates, the valve supplies a volume of toner in such a way that the toner in the toner reservoir fills a volume not more than a predetermined fraction of a maximum capacity of the toner reservoir. <IMAGE> |
