Abstract
In an image forming apparatus including a developing device storing a two-ingredient type or a one-ingredient type developer, a cleaning unit removes toner remaining on a photoconductive element after image formation. A toner conveying device conveys the toner collected by the cleaning unit to one or both of the developing unit and toner storing means. A powder pump includes a rotor and causes the rotor to rotate in order to move the collected toner in the axial direction of the rotor.
