摘要： A color image forming apparatus includes image forming units, an intermediate transfer body, and cleaning units. The image forming units form toner images of different colors. Each image forming units includes a developing unit supplying toner of each color. The toner images of the respective colors formed by the image forming units are primarily transferred onto the intermediate transfer body in a superposed manner. A toner image having been transferred onto the intermediate transfer body is secondarily transferred onto a recording medium. The cleaning units remove a residual toner on the intermediate transfer body. The cleaning units include first and second cleaning units. The first cleaning unit removes from the intermediate transfer body the largest amount of foreign matters, among all the cleaning units. A residual toner removed by at least the second cleaning unit is returned to one of developing units that supplies a black toner.

摘要： 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.

摘要： An image forming apparatus includes an image carrier, a cleaning device and a developing device. The cleaning device recovers a toner remaining on the image carrier. The toner recovered by the cleaning device is supplied to the developing device. The cleaning device includes a conductive brush member and an elastic blade. The conductive brush member is disposed on upstream of the image carrier in a rotation direction of the image carrier so as to be in contact with the image carrier. The conductive brush member recovers the toner remaining on the image carrier electrostatically. The elastic blade is disposed on downstream of the image carrier so as to be in contact with the image carrier. A toner recovered by the conductive brush member is supplied to the developing device and used in image formation again. A toner recovered by the elastic blade is discarded.
