In an intermediate transfer belt unit, elastic bodies are provided on respective inner circumferences of side edge portions of an intermediate transfer belt along with the circumferential direction. Rotating members are attached to respective opposite ends of a follower roller rotatably and concentrically with the follower roller, so as to face respective elastic bodies of the intermediate transfer belt. Each of the rotating members is composed of a tapered section, a bottom receiving section to keep bending of the intermediate transfer belt within a certain amount, a small diameter section forming an escape groove for receiving the elastic body of the intermediate transfer belt, and a large diameter section.
