徴とする画像形成装置の用紙分離装置。 A rotating shaft that is driven forward and backward by an intermittent drive means is provided so as to be movable in the axial direction parallel to the rotational axis of the photoreceptor, and as the rotating shaft rotates forward and backward, the tip of the claw is rotated. In a paper separating device of an image forming apparatus in which a rotating shaft is provided with a paper separating claw that comes into contact with and separates from the surface of a photoreceptor, a rotating shaft that is driven in synchronization with the rotating shaft by the intermittent drive means is rotated. A cam mechanism that is arranged parallel to the moving shaft and moves the rotating shaft in the axial direction as the rotating shaft rotates in either the forward or reverse direction via a one-way transmission means is connected to the rotating shaft and the cam. Provided between the mechanism holding member,
Further, an interlocking mechanism for moving the rotating shaft in the axial direction in conjunction with the axial movement of the rotating shaft is provided across the rotating shaft and the rotating shaft. Separation device.
