摘要：
A sheet stacking device has a discharging portion, a holding portion that holds a downstream end portion of the sheet, a stacking portion and a control portion that controls the discharging portion and the holding portion. The control portion controls at least one of the discharging portion and a holding portion so that the movement velocity of the holding portion is higher than the sheet discharge velocity of the discharging portion, and separates the sheet from the holding portion by using a velocity difference between the movement velocity and the sheet discharge velocity.
