Abstract:
A folding unit folds a sheet. A pressing unit presses a folded side of the folded sheet. A driving unit causes the pressing unit to slide in a direction perpendicular to a sheet conveying direction. A control unit independently sets number of slides at which the pressing unit is to slide on each of a plurality of sections of the folded side depending on a distance of each of the sections from a reference position, and controls the driving unit so as to slide in each of the sections for the number of slides set for that section.
