摘要：A sheet processing apparatus which perform a process to sheets comprising a stacking tray on which stacks the sheets to be performed a process; a discharge roller pair; a first path in which conveys a sheet to the discharge roller pair, shorter than the length of the minimum sheet size being conveyed in the sheet conveying direction; a second path branched from the first path and meeting with the first path at the upstream side in the sheet conveying direction of the discharge roller pair; and a path switching member, wherein a first sheet conveyed while processing the sheets on the stacking tray is guided into the first path by the path switching member, and when the front end of the first sheet projects from the discharge roller pair, the discharge roller pair is apart from each other and the first sheet is held in the first path, and the path switching member is changed over, and a second conveyed sheet is guided into the second path, when the front end of the second sheet projects from the discharge roller pair by a prescribed length, the discharge roller pair is closed to each other, and the first and second sheets are discharged onto the stacking tray in superimposed state by the discharge roller pair.
