Abstract
PURPOSE: To enable uniform electrostatic charge over the entire surface of a photosensitive body by setting a set space between the middle point of electrified wires and the surface of the photosensitive body wider than that between the both tip parts and photosensitive body.
CONSTITUTION: The distance between the middle point of both the electrified wires 2 and 3 and the photosensitive body 7 is set to a fixed distance A by putting tip parts 2b and 3b on the opposite sides of the electrified wires 2 and 3 close to the photosensitive body 7, making them cross relatively. On the other hand, as for the tip parts 2b and 3b of the electrified wires, the tip part 2b of the electrified wire 2 is closer than the tip part 3b of the electrified wire 3 to the photosensitive body 7 and the distance between the tip part 2b of the electrified wire 2 and the surface of the photosensitive body is set to A-x and the distance between the tip part 3b of the electrified wire 3 and the surface of the photosensitive body is set to A+x. Thus, the uniform electrification over the surface of the photosensitive body becomes possible by corona discharging, because the set space A between the middle point of the electrified wires 2 and 3 and the entire surface of the photosensitive body is set wider than the set space A-x at both the tip 2b and 3a.
