Abstract
An intermediate transfer belt assembly includes an intermediate transfer belt, a driving roller, a backup roller, a driving frame; and a backup frame. The driving roller and the backup roller spaced apart from each other to support and move the intermediate transfer belt in a first direction. The driving frame is to rotatably support the driving roller. The backup frame is connected to the driving frame, is to rotatably support the backup roller and is to move in the first direction.
