装置。[Claims for Utility Model Registration] (1) A paper peeling claw for peeling off paper attached to the circumferential surface of a rotating body can vibrate freely in the paper peeling direction with the tip of the claw in contact with the circumferential surface of the rotating body. A paper peeling device for an image forming apparatus, characterized in that the paper peeling device is provided with a claw vibrating mechanism for vibrating the paper peeling claw in the paper peeling direction. (2) To configure the claw vibrating mechanism, an arm having the paper peeling claw pivotally connected to one end side is connected to the rotational axis of the rotating body with the tip of the claw being urged into contact with the circumferential surface of the rotating body. A biasing device is attached to the arm so as to be swingable about parallel axes, and urges and swings the paper peeling claw in the paper peeling direction, and the paper peeling claw is repeatedly moved as the arm rotates. 2. A paper peeling device for an image forming apparatus according to claim 1, further comprising a rotating body with a protrusion that swings the paper in a direction opposite to the paper peeling direction. (3) The paper stripping claw according to claim (2), wherein the axis of the pivoting connection shaft of the paper peeling claw with respect to the arm is located closer to the rotating body than a tangent passing through a contact point of the tip of the claw with the circumferential surface of the rotating body. Paper peeling device for image forming apparatus.
