In the drawing, 1 is a photoreceptor of a copying machine or the like, and a toner image 2 developed by a developing device (not shown) is transferred onto a sheet of paper 4 by a transfer device 3. be done. In this transfer process, the next paper 4 is attracted to the surface of the photoreceptor 10.
After being neutralized by the separation corotron 5, the sheet 4 is peeled off by a peeling claw 6 whose tip is in contact with the surface of the photoreceptor 1, and sent to the next step, a fixing device (not shown).
The upper toner image is fixed onto the paper 4. - On the other hand, the peeling claw 6 has a substantially triangular shape with a sharp tip end, and is fixed to the shaft rod 7 at the base end side. Above shaft rod 7
is inserted into a long hole 8a bored in the machine frame 8, and can freely move forward and backward in the tangential direction of the photoreceptor 1 along the long hole 8a. A drive means 9, such as a lenoid, is connected to a part thereof, so that the peeling claw 6 can move forward and backward through the shaft rod 7.

れるようになっている。Further, a cleaning member IO is provided above the peeling claw 6 so as to be in contact with the upper surface of the peeling claw 6. The cleaning member 10 is impregnated with a lubricant such as petroleum-based lubricant, polyolefin, polyester, polyether, phosphate ester, fluorine-based or silicone-based lubricant, lubricating grease, or surfactant, as shown in FIG. As shown in Figure 4, rolls of felt or paraffin solids formed into a flat plate are used, and as the peeling claw moves back and forth, the toner adhering to the tip of the peeling claw is wiped off. It is now possible to do so.

In this case, it is effective in peeling off paper stuck to the fixing roll of the fixing device. That is, it is possible to prevent paper damage and paper jams caused by toner melted by the surface temperature of the fixing roll adhering to and solidifying on the lower surface of the peeling claw 6.

費の大幅な低減が図れるようになった。Effects of the Invention As described in detail above, the present invention allows the peeling claw 6 to move forward and backward in the direction of contact and separation from the photoreceptor 1, and when the peeling claw 6 retreats, the cleaning member IQ provided in contact with the peeling claw 6 cleans the peeling claw. Since the toner adhering to the tip of the peeling claw 6 is wiped off, it is possible to completely prevent untransferred toner from adhering and accumulating on the tip of the peeling claw 6. This can prevent image quality from deteriorating due to damage to the surface of the photoreceptor 1 caused by the toner solidified at the tip of the peeling claw 6. By the way, with conventional peeling claws, a decrease in image quality was observed after 20,000 to 50,000 copies were made, but with the peeling device of this invention, there is no decrease in image quality until 100,000 copies are made, and the maintenance effort is reduced. It has become possible to significantly reduce costs.
