PROBLEM TO BE SOLVED: To provide an image forming device that cools efficiently a sheet bundle on a sheet discharge tray part 50 so as to prevent the sheet discharge tray 50 from being heated by residual heat of the sheet bundle without impairing stack performance of a sheet to be discharged onto the sheet discharge tray part 50.SOLUTION: On an upper surface of a sheet discharge tray part 50 are formed a plurality of rib parts 51 that are extended along a sheet discharging direction and arrayed at intervals from each other in a direction orthogonal to the sheet discharging direction; in a wall part 60a, in which a sheet discharge port 60f in an enclosure 60 is formed, are formed opening parts 60g communicating the adjacent rib parts 51; and in the enclosure 60 is provided a suction fan 72 that suctions outside air of the enclosure 60 through the opening parts 60g. |
