PURPOSE: To reduce cost and to improve assembly property by forming the titled claw in a semicircular arc shape, fixing one end to a machine body side, forming a claw tip part in the other end and making it contact elastically to the surface of a photosensitive body, and providing a circular arc part and a straight part on the upper part of the separating claw.

CONSTITUTION: A separating claw 16 is made of a plate spring, has a shape which has provided a linear claw part 16b and a fitting part 16c on the tip side of a semicircular arc-shaped part 16a and the rear end part, respectively, and it is constituted so that an angle α made by the claw part 16b and a tangent line in a connecting part to a photosensitive body is 5°, a tip displacement distance between a state that it is not contacting to the photosensitive body, and a contact state is about 1mm, and a pressure between the separating claw 16 and the photosensitive body 1 becomes ≤3g. Accordingly, a spring constant is low, and also the structure is strong against buckling of the time of an abnormal load. In this way, this claw can be prepared at a low cost, and also the life can be further extended by performing a resin covering to the tip part.
