<p>A scale is provided on a back side edge of an intermediate transfer belt for detecting an amount of movement of the belt (10). In a tandem type image forming apparatus, a sensor is provided as a scale-reading unit that reads the scale. Materials used for the intermediate transfer belt (10) and the scale satisfy a relation that the Young's modulus of the intermediate transfer belt is greater than the Young's modulus of the scale (70). <IMAGE></p> |
