ABSTRACT:
An image forming apparatus includes: an electrostatic latent image bearing member; a toner cartridge; a developing member; a transfer member; a developing device; a toner-circulating member; a drive-force output unit; and a circulating-member driving unit. The toner cartridge is removably coupled to the developing device. The toner-circulating member is incorporated in the developing device and circulates toner between the developing device and the toner cartridge. The drive-force output unit is provided in the toner cartridge and is configured to output to the developing device a drive force for driving the toner-circulating member. The circulating-member driving unit is provided in the developing device and is configured to drive the toner-circulating member upon receiving the drive force outputted from the drive-force output unit while the toner cartridge is being coupled to the developing device.
