摘要： PROBLEM TO BE SOLVED: To minimize loss of limited frictional force serving as a source of steering force for effectively functioning an automatic centering mechanism when a sliding member at the end has a low friction factor for reducing main scanning position displacement due to centering in belt automatic centering using a balance of frictional force. SOLUTION: In the belt automatic centering using a balance of frictional force, a steering roller is used as a tension roller pressed by a biasing means. The steering roller is disposed so that a geometric suspension condition of an elliptical locus c through which the steering roller is locked, a distance L A between an upstream suspension roller and the steering roller, and an angle ϕ made by the distance L A and a distance L C between the upstream and downstream suspension rollers satisfies either of expressions 0 ϕ>125°.
