ABSTRACT:
In a belt apparatus used for image formation structured such that processing unit used for image formation are placed around a belt extended between at least two rollers and at least one of the processing unit acts on a roller so as to impart a rotational load thereto, it is possible to avoid a reduction in the image quality of a transfer image on the belt caused by the roller that supports the belt receiving variations in the load due to the movement towards or away from the belt of a cleaning blade. A drive source is connected to the roller to which directly receiving the load variation making this roller the drive roller for the belt.
