A sheet eject device is provided for detecting whether a sheet eject tray is filled with ejected sheets. The sheet eject device includes an ejecting unit that ejects sheets onto the sheet eject tray; a counting unit that counts an accumulated eject number every time a sheet is ejected by the ejecting unit; a storing unit that stores a defined eject number threshold and a defined eject interval time; a fullness detecting unit that detects that the sheet eject tray is filled with ejected sheets when the accumulated eject number counted by the counting unit exceeds the defined eject number threshold; and a reset unit that resets the accumulated eject number counted by the counting unit when an eject interval time exceeds the defined eject interval time, the eject interval time extending from when one sheet is ejected until a next sheet is ejected by the ejecting unit. |
