摘要：
A belt member is supported by a plurality of rollers and moves in a predetermined moving direction. A detecting unit detects a displacement of the belt member in its width direction. A correcting unit moves a second end of a first roller from among the rollers in either one of a forward direction and a backward direction while fixing its first end based on a result of detecting the displacement of the belt member such that a tilt of a rotating shaft of the first roller is changed to correct a meandering of the belt member. An adjusting unit adjusts a fixing position of the first end.
