Belt conveyor with regulation member to regulate movement of conveyor belt, and image forming apparatus equipped therewith

摘要

A belt conveyor includes a driving roller, a driven roller, a conveyor belt wound around the driving roller and driven roller to run endlessly by rotation of the driving roller, and a pair of regulation members arranged adjacent to both the ends of the axial direction of the driving roller to regulate movement of the conveyor belt in the axial direction of the driving roller. The conveyor belt has a conveying portion which conveys an image receiving medium and a returning portion which returns from an ending position of the conveying portion to a starting position of the conveying portion. The pair of regulation members each have a regulating surface that is arranged at a position able to contact a side edge of the conveyor belt at only the returning portion side of the conveyor belt below a middle position between the conveying portion and the returning position where the conveyor belt winds around the driving roller.
