CORONA DISCHARGING DEVICE

PURPOSE: To simplify maintenance work such as cleaning or replacing a discharge electrode part by arranging an integrated electrode at a specified distance from a photoreceptor and providing the electrode so that it can be attached to/detached from an insulating supporting body having elasticity. CONSTITUTION: The stainless tooth-shaped discharge electrode 8a is disposed on the insulating substrate 8b. A common electrode 8h is installed on an opposite side to the electrode 8a on the substrate 8b. By attaching a common electrode projected part 8i to the center of a chip resistance 8c knocked in the electrode 8a in a shape functioning as positioning, the electrode 8a is fixed Then, the electrode 8a is fixed. The electrode 8a is mounted on the substrate 8b so that its addendum may be positioned to be projected to a photoreceptor side from the edge part of the substrate 8b. The common electrode 8h is connected to a high voltage power source, and high voltage is impressed on the electrode 8h by the high voltage power source, thereby generating corona discharge from the addendum and electrifying the surface of the photoreceptor.
