IMAGE FORMING APPARATUS

摘要

An image forming apparatus includes an image carrier and a cleaning device. The image carrier is rotated to carry a toner image. The cleaning device includes a cleaning member and an auxiliary cleaning member. To the cleaning member, a bias of a reversed polarity to a polarity of a remained toner adhered on a surface of the image carrier is applied. The auxiliary cleaning member is located at an upstream side from the cleaning member in a rotating direction of the image carrier. According to advance of whitening of the surface of the image carrier, the auxiliary cleaning member is made to come into contact with the surface of the image carrier or contact pressure of the auxiliary cleaning member with the surface of the image carrier is increased.
