Abstract
A belt driving controller includes a driving roller having a radius r1, a plurality of driven rollers that is driven by rotation of the driving roller, the driven rollers having a radius r2, an endless belt that is wound on the driving roller and the driven rollers and an encoder that is attached to one of the driven rollers, and that outputs a signal. The rotation of the driving roller is controlled based on the signal from the encoder, and (α2/α1)×(r1/r2)≦1 is satisfied where α1 is a correction coefficient for a fluctuation in thickness of the endless belt caused by a belt winding angle on the driving roller, and α2 is a correction coefficient for a fluctuation in the thickness on the driven roller.
