Abstract
In a belt driving device, the width of a belt member is larger than the width of a driven roller portion in the rotation axis direction of the driven roller portion. The belt driving device includes a movement unit configured to, when a load is generated in friction members at both ends of the driven roller portion, rotate and move the friction members in a direction opposite to the moving direction of the belt member.
