PROBLEM TO BE SOLVED: To stabilize kicking-out of a sheet by a pair of knurling belt rollers in a finisher using knurling belts for ejecting and pulling a sheet to a process tray. SOLUTION: The rotational speed of the knurling belt is kept same as the ejecting speed until the rear end of an ejected sheet drops and stands still on the process tray. A traction means for drawing the knurling belt according to the number of sheets is provided. The speed of ejecting sheet is changed so that the jumping amount of the rear end of the sheet ejected from the outer peripheral surface of the downstream side knurling belt, variable according to the drawing amount, can be made constant. |
