ABSTRACT:
A belt meandering motion correcting device includes a belt tension enhancer for enhancing the tension of a side of the belt which undergoes a deviation, and a control roller around which the belt is wound and which allows a side portion of the belt where tension has increased to be displaced toward the downstream side in the moving direction of the belt. Accordingly, a side portion of the control roller on the side where tension has been enhanced, i.e., the side where a deviation has occurred, is displaced toward the downstream side in the moving direction of the belt, and is thereby guided in an opposite direction to the deviating direction of the belt.
