Abstract
A postprocessing apparatus includes a stacking unit that stacks a sheet, an abutting unit that corrects a conveying direction of the sheet, a return roller that abuts the sheet against the abutting unit, a shift conveying unit that shifts the sheet in a width direction, and a width direction detector that detects a width direction position of the sheet. When the sheet is shifted by the shift conveying unit by a predetermined amount, passed to the return roller, and abutted against the abutting unit, distances A and B are nearly the same, where the distance A is a distance from a conveying direction position of a side of the sheet to a rear end of the sheet and the distance B is a distance from the return roller to the abutting unit.
