摘要：
A sheet ejection device including: a sheet stacking section; a sheet trailing edge hitting section; a pair of sheet holding members for holding a sheet or plural sheets placed one on top of another at a sheet holding position, and moving the same to the sheet stacking position; and a friction member that is provided on one of the sheet holding members and that comes in contact with the topmost sheet of the sheets stacked on the sheet stacking section; wherein, when the sheet holding members reach the sheet stacking position, one of the sheet holding members is moved upstream in the sheet ejecting direction, whereby the trailing edge of the held sheet is made to hit against the sheet trailing edge hitting section, and the friction member comes in contact with the topmost sheet, and then the topmost sheet is biased toward the sheet trailing edge hitting section.
