ABSTRACT:
An electrophotographic image forming apparatus including a developing unit operable with a one- or two-ingredient type developer and a device for replenishing toner to the developing unit included in the apparatus are disclosed. A plurality of toner bottles are accommodated in the toner replenishing device, so that the toner is replenished from one toner bottle to the developing unit. A rotating mechanism causes all the toner bottles to rotate during toner replenishment. A device is provided for determining the frequency of use of the individual toner bottle. The toner discharged from each toner bottle is fed to a toner transport portion via a respective passageway.
