。[Claims for Utility Model Registration] After repeating the process of forming a toner image on a rotating image carrier by charging, exposure and development with toner and transferring the toner image to a rotating intermediate transfer member multiple times, The overlapping toner images are transferred onto a transfer material, and after the transfer, a cleaning member is brought into pressure contact with the intermediate transfer member to clean the intermediate transfer member, and after cleaning, the cleaning member is separated from the intermediate transfer member, and the image is removed. In an image forming apparatus for forming an image forming apparatus, a charging unit charges toner remaining on the intermediate transfer body when the cleaning member is separated from the intermediate transfer body with a polarity opposite to that of the image carrier. An image forming apparatus characterized in that: is provided on the downstream side of a position where the cleaning member comes into pressure contact with the intermediate transfer member in the rotational direction of the intermediate transfer member.
