Abstract
An image forming device and a belt device therein are provided. Even though the perimeter of the intermediate transfer belt is changed, a good cleaning ability for the intermediate belt can be maintained. The toner image supporting surface of the intermediate transfer belt between the first and the secondary transfer devices is bent to the inner surface side by a bending member, and cleaned by a cleaning device. An opposite member is disposed at a position opposite to the cleaning device to sandwich the intermediate transfer belt. In this way, even though the position of the bending member is changed by the perimeter deviation of the intermediate transfer belt, the position for removing the residual toner to clean the intermediate transfer belt does not change, so as to maintain a good cleaning ability.
