PURPOSE:To eliminate the jam of the toner accumulated in a pawl part and to prevent the sticking of the toner on paper, by narrowing the front end of the pawl which peels the paper from a fixation roll and bulging the central part thereof. CONSTITUTION:A roll type fixation device 1 fixes the toner image 13 on paper 12 with a heating roll 2 and a pressurizing roll 3. The paper 12 after fixation is peeled from the roll 2 by the front end 6 of a peeling pawl 5, and is discharged by a pinch roll 10 and a discharging roll 11. The front end 6 of the pawl 5 scrapes the toner on the peripheral surface of the roll 2 with its edge 6c. The toner sticking on the edge 6c moves in the same X direction as the advancing direction of the paper 12. Notches are formed on both sides of the part 6b of the peeling pawl and a bulged part 6a is provided in the central part thereof. Therefore the toner moving in the X direction is accumulated in the notched parts 6b. Since the sticking of the toner on the bulged part 6a in the central part is prevented by said notched parts, the sticking of the toner on the paper 12 is obviated. |
