Abstract
An image forming apparatus includes a replaceable toner cartridge filled with toner, a toner supplying unit, and a control unit. The toner supplying unit supplies toner from the toner cartridge to a developing device of the apparatus. The control unit exerts control so that, when the toner cartridge is mounted in the apparatus, the toner supplying unit is driven based on the amount of toner with which the mounted toner cartridge is filled in advance. The expression T1>T2 is satisfied, where T1 represents a driving time for the toner supplying unit driven based on the amount of toner with which the toner cartridge mounted upon initial installation is filled in advance, and T2 represents a driving time for the toner supplying unit driven based on the amount of toner with which the toner cartridge mounted newly when no toner is detected is filled in advance.
