PROBLEM TO BE SOLVED: To provide an intermediate transfer belt with excellent durability which forms a high-quality image without causing running failure and image unevenness caused by warpage of the belt, and an image forming apparatus including the intermediate transfer belt.SOLUTION: On a polyimide laminated intermediate transfer belt, a toner image obtained by developing a latent image formed on an image carrier with toner is transferred. The intermediate transfer belt includes an inner layer formed of a base material layer, and an outer layer formed on the base material layer. The base material layer contains polyimide having a structural unit derived from pyromellitic acid and a structural unit derived from diaminodiphenyl ether, at least. Warpage to the inside of the intermediate transfer belt is 1.0 to 10.0 mm. |
