    摘要： A sheet conveyance unit includes first and second conveyance rollers facing each other, a first stopper provided at an axial end portion of the first conveyance roller, projecting radially beyond a circumferential surface of the first conveyance roller, downstream rollers positioned downstream from the first and second conveyance rollers in a sheet conveyance direction, an engaging and disengaging unit to disengage the first and second conveyance rollers from each other, and a controller. The first stopper rotates to a contact position projecting into the sheet conveyance path and to a non-contact position away from the sheet conveyance path as the first conveyance roller rotates. The first stopper moves to the non-contact position after stopping a sheet. The first and second conveyance rollers are disengaged from each other after a leading end of the sheet reaches the downstream rollers, before the first stopper moves to the contact position.

    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.
