Abstract
PURPOSE:To enable copying with minimum picdure unevenness, by uniforming the distribution of luminous intensity of de-electric light to the photoreception drum plane and minimizing the de-electricity unevenness. CONSTITUTION:The light source lamp 7 for de-electricity is provided in parallel with a given interval toward the width of the photoreception drum at the part opposing to the surface of the photoreceptor drum 1. Further, the optical filter 8 is provided in front of the photoreceptor drum 1 of the light source lamp 7, and this and the light source lamp 7 are equipped in the case 9, and fitted under the case of the cleaning device together with the de-electricity corotoron 10. Further the light shield members 14a, 14b, 14c, 14d... are provided to be orthogonal to the center shaft lengthwise of the lamps 7a, 7b, 7c, 7d.... Thus, the distribution of luminous intensity reaches almost uniform, uniforming the effect of de-electricity to the drum 1.
