    摘要： A sheet processing apparatus (2) includes: a folding unit (215, 230) that folds a sheet bundle (SB); a pressing unit (260) that presses a fold part of the sheet bundle (SB), which has been folded by the folding unit (215, 230), in a thickness direction of the sheet bundle (SB) to enhance folding of the fold part; and a moving unit (263) that advances and returns the pressing unit (260) in a width direction of the sheet bundle (SB). The pressing unit (260) starts pressing from a predetermined position in the width direction of the sheet bundle (SB) during advancing movement, and releases pressing after going past one end of the sheet bundle (SB). The pressing unit (260) starts pressing from the predetermined position during return movement and goes past the other end of the sheet bundle (SB).

    摘要： A pressing unit presses a folded side of a stack of sheets folded by a folding unit (74, 81), thereby making a strong crease on the stack of sheets. The pressing unit includes a pressure roller (600) that slides on the folded side while rotating, an elastic biasing unit (609) that presses the pressure roller (600) in a thickness direction of the stack of sheets, and a driving unit (606, 607, 612) that slides the pressure roller (600) in a direction substantially perpendicular to a conveying direction of the stack of sheets. A lifting unit (602, 611), when the pressure roller (600) slides to a first position, temporarily lifts up the pressure roller (600), and when lifted-up pressure roller (600) slides to a second position, lifts the lifted-up pressure roller (600) down onto the folded side. The first position and the second position are located before a corner of the folded side, whereby the pressure roller (600) cannot slide up on the folded side.
