Abstract
PURPOSE: To make the suction and exhausting of ion wind good and even by comparing the potential in the central part in the lengthwise direction of the two side faces of a conductive shield not opposing to a photoreceptor with the potential at the end part in the lengthwise direction and making these relatively close to the potential of a discharge electrode.
CONSTITUTION: A conductive shield 11 consists of a back plate 11b opposing to a photoreceptor 3 and parallel side plates 11c, 11c which do not opposite thereto. Insulation members 18 are secured on the insulation plates 16 bonded to the plates 11c, over the length l in the central part in the lengthwise direction of a discharge device 1. The members 18 are provided nearly sysmmetrically on the right and left, with discharge wires 14 in-between and the length l is selected within the specified range with respect to the effective discharge length L of the device 1. The width of the members 18 is so determined that the position relations of the wires 14, shield 11 and photoreceptor 3 are set in such a manner that at the time of discharging the corona current flows more toward the shield 11 than toward the photoreceptor 3.
