A sheet discharging device includes a shift trayon which a sheet P1 is stacked, a discharging rollerthat discharges a sheet P2 onto the shift tray, a blowing devicethat sends air to a lower surface of the sheet P2 discharged by the discharging roller, a blocking memberthat blocks air sent to the lower surface of the sheet P2 from a blowing port-of the blowing device, and a control unit that controls the blocking amount of the blocking member. The blocking amount is determined based upon sheet information including sheet-type information, sheet-size information, and sheet-thickness information, for example.

In a sheet creaser, a sheet set is pushed between a pair of folding rollers to fold the sheet set. Then, a re-pressing roller re-presses the sheet set, which has been folded by the folding rollers, by rolling along the crease. Pressure applied on the sheet set by the folding rollers is released when the re-pressing roller re-presses the sheet set.
