ABSTRACT:
An image forming apparatus includes a latent-image carrier, a developing unit, a transfer unit, a cleaning unit, a recovered-toner supply unit, and a foreign-matter collecting unit. The developing unit carries a developer containing a toner and develops an electrostatic latent image on the latent-image carrier with the toner. The transfer unit transfers the toner developed on the latent-image carrier to a recording material directly or via an intermediate transfer body. The cleaning unit removes a toner remaining on at least one of the latent-image carrier and the intermediate transfer medium after the transfer. The recovered-toner supply unit supplies a toner removed by the cleaning unit to the developing unit again. The foreign-matter collecting unit collects a foreign matter, which is mixed into the toner supplied from the recovered-toner supply unit and moved onto the latent-image carrier by the developing unit, before the transfer by the transfer unit.
