An intermediate transfer belt includes, on a surface in contact with a photosensitive drum and a cleaning blade, a plurality of grooves formed along a moving direction of the intermediate transfer belt in a width direction which intersects the moving direction of the intermediate transfer belt. Further, the intermediate transfer belt includes a plurality of first regions in which adjacent grooves in the width direction are arranged at a predetermined interval, and a second region which is positioned between the plurality of first regions and in which an interval between adjacent grooves in the width direction is different from the predetermined interval. The second region is arranged outside, in the width direction of the intermediate transfer belt, a range in which a patch toner is to be formed in concentration correction.
