Abstract: A transporting device includes steering rollers, a center roller which is disposed between the steering rollers and deflection-detecting sensors that are positioned downstream from the steering rollers. When a sheet of paper has a width which is narrower than a width of a reference sheet of paper, the positional deflection of the sheet of paper is corrected by transporting the sheet of paper to a shift roller with the sheet of paper being nipped by the center roller and thrusting a forward end of the sheet of paper against a shift roller. When a sheet of paper has a width which exceeds the width of the reference sheet of paper, the positional deflection of the sheet of paper is corrected by rotating the steering rollers separately based on a detected result of the sensors with the sheet of paper being nipped by the steering rollers.
