Abstract

PURPOSE:To prevent a wrong exchange demand when a developer can't be replenished properly by forcibly making up the developer in a certain time when the emptiness of the developer is detected, and afterward displaying the exchange demand of a developer replenishing art when the emptiness is again detected later on. CONSTITUTION:When developer concentration detected by a concentration detecting device 70 reaches a prescribed, concentration, the emptiness of the developer in a toner cartridge 67 as the developer replenishing part is detected and when the detection is performed, the forcible making-up of the developer by the developer replenishing part 67 is performed in the certain time. After the forcible making-up is performed, when the emptiness of the developer in the developer replenishing part 67 is again detected, the exchange demand of the developer replenishing part 67 is displayed. Thus, when the developer can't be replenished properly according to the change of the consumption amount of the developer can be performed, corresponding parts can be protected.
