Abstract:
A belt device includes a belt member, a detecting unit, and a preventing member. The belt member is stretched over a plurality of rollers and moves in a predetermined moving direction. The detecting unit detects deviation of the belt member in a belt width direction of the belt member. The preventing member is arranged near the detecting unit and prevents deviation of the belt member in a direction other than the moving direction and the belt width direction.
