ABSTRACT:
An electrophotographic image forming apparatus includes an electrostatic latent image carrying body, an electric charger for uniformly electrifying the carrying body, an optical exposure unit to form an electrostatic latent image on the carrying body, a developer for developing the electrostatic latent image to form a toner image on the carrying body, a transfer unit for transferring the toner image from the carrying body onto a printing sheet, a fixing unit for fixing the toner image to the printing sheet, a cleaner for cleaning to remove residual toner from the carrying body and a toner returning mechanism for returning the residual toner removed by the cleaner to the developer. The developer includes a housing in which a toner chamber is defined, a developing roller rotatably mounted in the housing, an agitator rotatably mounted in the housing so as to be positioned in the toner chamber, a partitioning member provided in the housing for defining a carrier chamber adjacent to the developing roller. The toner returning mechanism includes a toner recirculator for recirculating the residual toner removed from the carrying body to the toner chamber.
