    Patent number: 8398079
    Abstract: A control portion controls a skew feed correcting portion so that a first skew feed correcting operation for correcting skew feed of a sheet while turning the sheet based on one edge of the sheet crossing a sheet conveying direction is performed in a case where a first alignment operation based on a position of one edge of the sheet is performed when a sheet processing portion processes the sheet. Further, the control portion controls the skew feed correcting portion so that a second skew feed correcting operation for correcting the skew feed of the sheet based on a side edge of the sheet parallel to the sheet conveying direction is performed in a case where a second alignment operation based on a position of the side edge of the sheet is performed when the sheet processing portion processes the sheet.
