Abstract
An image forming apparatus of the type collecting a toner remaining on the surface of an image carrier after image transfer and returning it to a developing unit to use it again. The apparatus separates the toner from paper dust and other impurities before returning the toner to the developing unit on the basis of differences in charge, weight and volume between the toner and the impurities. The toner is returned via an eletrostatic conveyor.
