摘要
A sheet stacking device includes: a pair of sheet discharge rollers having a drive roller; a stacking tray for stacking sheets; a blade member; and a controller. The controller executes: stop processing in which the blade member is stopped at a stop position during discharging of the sheet; and rotation processing in which the blade member is rotated by one turn before a rear end of the sheet passes through the pair of sheet discharge rollers and the sheet is placed on the stacking tray. The blade is configured, in the rotation processing, to make the sheet fall on the stacking tray by beating a rear end portion of the sheet from above, and to be brought into contact with the rear end portion of the sheet which falls on the stacking tray from above while pulling the sheet toward an upstream side in the sheet discharge direction.
