PROBLEM TO BE SOLVED: To provide an intermediate transfer belt structure which prevents the stuck part of the reinforcement member from flaring like a bell and has excellent durability free of meanders in the intermediate transfer belt made of a synthetic resin stuck a reinforcement member for reinforcing ends of the belt, and to provide a method for manufacturing the belt. SOLUTION: The intermediate transfer belt 1 in the form of an annular seamless belt has an inner bend part 1a as a small diameter part whose diameter in an image formation area gradually decreases toward one end, in the vicinity of the right and left ends in the axial direction of its cylinder, and an outward bend part 1b as a large diameter part whose diameter gradually increases towards the other end. The reinforcement member 2 is stuck to the external surface of the inner bend part 1a, and a guide rubber 3 for preventing meander is stuck to the internal surface of the part. In the method of the production of it, an annular belt intermediate body is mounted inside a mold having a shape corresponding to the inner and outer bend parts 1a and 1b, and is heated to a temperature right above the glass transition point of a resin forming the belt intermediate transfer body, thereby transferring the shape of the mold to the belt intermediate body.
