。[Claims for Utility Model Registration] 1. A corona discharge wire is disposed within a conductive shield case having a discharge opening, and the corona discharge wire is exposed to light through the discharge opening of the shield case. In an electrophotographic corona discharger disposed so as to be movable relative to the photoreceptor so as to face the body, the discharge opening of the shield case is the opening of the shield case facing the body with the corona discharge wire in between. A slit is provided on the side surface of the corona discharge wire so as to face the discharge region of the wire except for each end, and a slit is provided on the inner circumferential surface of the side surface of the shield case corresponding to the downstream side in the direction of movement of the photoreceptor. What is claimed is: 1. A corona discharger for electrophotography, characterized in that the insulator is insulated; 2. The electrophotographic corona discharge device according to claim 1, wherein each end of the corona discharge wire in the discharge region has a length of 10 mm or more.
