置。 A plurality of corotron wires for transfer and peeling, with the photosensitive drum as a counter electrode, are stretched in the width direction of the drum near the photosensitive drum, and corona discharge between the plurality of corotron wires and the photosensitive drum causes a discharge on the photosensitive drum. In a corona discharge device for a copying machine, which transfers toner onto paper and peels the paper from a photosensitive drum, a conductive sheet surrounding the plurality of corotron wires except for the discharge portions of the corotron wires is provided. 1. A corona discharge device for a copying machine, characterized in that a shield member made of a magnetic plate is provided, a portion of the shield member is cut and raised, and the cut and raised portion is located approximately in the middle of the plurality of corotron wires.
