PURPOSE:To permit maintenance of stripping performance for a long period of time without damaging the surface of a photosensitive body by forming the front end side of a pawl member on the side where the member does not contact the photosensitive body to a hollow curved shape having gradually increasing thicknesses and forming the end part side at the front end of the pawl member to a projecting curved shape. CONSTITUTION:The base 3 side in the front end part of the pawl member 1 is formed to the hollow curved shape having the thicknesses increasing gradually from the front end side toward the root end side and, therefore, the paper P conveyed according to the movement of the photosensitive drum 7 is guided in approximately the same direction as the conveyance direction of the drum 7 right after the collision and is then gradually guided to the lower side when the front end of the above-mentioned paper P collides against the front end of the awl member 1. Since the component of force F2 of the impact force F1 at this time decreases,the drum 7 is hardly flawed. In addition, shapes on the end part 1a, 1b side of the front end is formed to the projecting curved shape and, therefore, even if said end contacts the drum 7 surface, the drum 7 is hardly flawed and the stripping performance is maintained for a long period of time. |
