Abstract
A belt driving device includes an endless belt; support members that extend in a width direction of the endless belt and support the endless belt, the support members including a control member that controls the widthwise position of the endless belt; a support body that supports the support members; and a driving mechanism that drives one end of the control member to cause the control member to pivot about a pivot axis in a direction in which stretching of the endless belt is prevented. A portion of the control member shifted from the midpoint toward an edge of the endless belt is pivotably supported by the support member to serve as the pivot axis, so that the moving distances of two points on the control member aligned with the edges of the endless belt when the control member is driven by the driving mechanism are close to each other.
