Abstract
A belt tracking system for adjusting misalignment of a movable belt in an axial direction of a plurality of rollers about which the movable belt is entrained includes a slope member and a stationary shaft guide. The slope member is disposed at both ends of at least one of the plurality of rollers in the axial direction, to tilt the roller as the belt moves in the axial direction. The stationary shaft guide contacts the slope member. A distance between a contact point of the slope member that contacts the stationary shaft guide and an end portion of the slope member in the axial direction is longer than a maximum traveling distance that the slope member travels in the axial direction.
