Abstract
A sheet stacking device includes: an evacuation section for transporting and ejecting sheets; a sheet exit tray for stacking the ejected sheets; an arm supporting member; and a sheet presser arm including a supported end at one end, a free end at the other end which is capable of pressing the sheets stacked on the sheet exit tray directly or via a contact member attached to the free end, and a flexure portion having flexibility between the supported end and the free end. The supported end is attached to the arm supporting member. The arm can apply, by the flexibility of the flexure portion, a pressing force to the sheets stacked on the sheet exit tray and a repulsive force to each of the ejected sheets when a front end of the ejected sheet strikes against the arm.
