Abstract
A belt feeding unit includes a rotatable belt, a first stretching roller for stretching the belt, and a second stretching roller including a stretching portion for stretching the belt. A first member is provided at one end portion of the stretching portion with respect to a widthwise direction of the belt and perpendicular to a movement direction of the belt. The first member is movable relative to the stretching portion to change a position of one end of the stretching portion at the one end portion. In addition, a second member is provided at the other end portion of the stretching portion and is movable relative to the stretching portion to change a position of the other end of the stretching portion at the other end portion. When the belt shifts in the widthwise direction to contact the first member, the first member moves relative to the stretching portion to incline the stretching portion relative to the first stretching roller, and the second member does not prevent movement of the stretching portion by the first member.
