の用紙剥離装置。[Claims for Utility Model Registration] (1) A toner image formed on the surface of a photoreceptor drum is transferred to paper by a transfer device, and
A device for peeling the transferred paper from the surface of the photoreceptor drum by a peeling device disposed adjacent to the transfer device, wherein the peeling device has a serrated or needle-like tip and is attached to the photoreceptor drum. Consisting of opposing pointed electrodes, the pointed electrodes are covered with an insulator so that only the portion facing the photoreceptor drum is exposed, and are connected to a constant current power supply to apply voltage to the transfer device. A paper peeling device for an electronic copying machine, characterized in that it is configured to apply a voltage of opposite polarity set in the range of 1/5 to 1/15 of the total discharge current. (2) The constant current power supply device has a limit voltage set and is controlled so as not to generate spark discharge between the constant current power supply device and the photosensitive drum. paper peeling device for electronic copying machines.
