A belt feeding apparatus includes an endless belt and a supporting member for rotatably supporting the belt. The belt feeding apparatus further includes a setting member for setting, when the belt is deviated from a widthwisely normal zone, an inclination angle of the supporting member to a return angle to return the belt toward the normal zone. The setting member also sets, when a predetermined time elapses from the belt returning to the normal zone, the inclination angle of the supporting member to a balance angle to keep the belt in the zone.
