Abstract
A belt feeding apparatus has a rotatable belt, first and second belt stretching members, and a steering unit which has a rotatable portion rotatable with rotation of the belt, a frictional portion, and a supporting portion for supporting the rotatable portion. The frictional portion is provided with an inclined surface so that the distance between the rotational axis of the rotatable portion and the surface of the frictional portion increases toward an outside with respect to the direction of a rotational axis of the rotatable portion, and a length of the belt member with respect to the rotational axis direction of the rotatable portion is longer than a length of the rotatable portion and is shorter than a sum of the lengths of the rotatable portion and the frictional portions provided at respective ends, and the belt member contacts both of the frictional portions simultaneously.
