Abstract
A sheet finishing apparatus includes: a conveying roller configured to convey a sheet to a storage tray; a positioning stopper provided in parallel to a conveying path for the sheet; an aligning roller configured to convey the sheet, move the sheet in a lateral direction orthogonal to a direction of the conveyance, and press the sheet against the stopper to laterally align the sheet; and a moving mechanism configured to move the position of the aligning roller in the conveying direction. The sheet finishing apparatus controls the position of the aligning roller according to a size of the sheet.
