Abstract
A belt drive used in image forming apparatuses which minimizes the transverse movement of the belt across the length of a roller and prevents the riding up of the belt onto the roller. The belt drive device has a belt equipped with elastic guide members mounted on each edge or on the back surface of the belt near each edge. The belt is suspended over two or more rollers and driven by the drive belt. At least one of the rollers is a drive roller having a rotating member mounted between the elastic guide member and the roller end area such that the rotating members rotate independently of the roller.
