The sheet ejecting apparatus 10 further includes a motor 24 for shifting the top roller 21 to switch between pressing state and separated state with respect to the ejecting roller pair 15 and a controller 20 for controlling the motor 24 . The controller 20 works as ejection means that makes the ejecting roller pair 15 pressing state so as to eject a sheet stack and as separation means that makes the ejecting roller pair 15 separated state before a back end of a sheet stack escapes from nips of the ejecting roller pair 15 by using the motor 24.
