After an image forming unit (14) forms a plurality of page images on a first side of the sheet, a cutting unit (6) cuts off the sheet. Then, for image formation on a second side opposite the first side, a duplex conveying unit (9) conveys the sheet to the conveying unit, with a second end of the sheet as the leading end. The second end is opposite the first end and has been formed by cutting off the sheet. In image formation only on the first side, the sheet is cut off at a first position behind the last page image formed on the first side.
