An intermediate transfer unit includes an intermediate transfer belt, a plurality of rollers, a cleaning unit, a brush unit, and a pressing member. The brush unit is located at the outer circumferential surface part of the intermediate transfer belt in contact with the roller. The brush unit is located at upstream of a contacting part with the cleaning unit in a running direction of the intermediate transfer belt. The brush unit is configured to impart electric charge to the remnant toner by a contact friction with the outer circumferential surface of the intermediate transfer belt. The pressing member is configured to press the brush unit along a direction of contact/separation with respect to the outer circumferential surface of the intermediate transfer belt.
