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.
