PROBLEM TO BE SOLVED: To provide good stacking properties when a sheet is blown and discharged, and to prevent entry of a foreign matter into a blowing port.SOLUTION: A sheet discharging device includes: a shift tray 202 for stacking a sheets P1; a discharging roller 6 for discharging a sheet P2 onto the shift tray 202; a blowing device 230 for sending air to a lower surface side of the sheet P2 discharged by the discharging roller 6; a shielding member 231 for shielding air sent to the lower surface side of the sheet P2 from a blowing port 230-2 of the blowing device 230; and control means for controlling the shielding amount of the shielding member 231. The shielding amount is determined on the basis of paper information including sheet-type information, sheet-size information, and sheet-thickness information, for example. |
