摘要： PURPOSE:To weaken the ionic wind and to prevent deterioration of a photosensitive body by dividing a grid of an electrostatic charging device into plural grids, and impressing each different voltage which becomes higher successively in the advancing direction of the photosensitive body. CONSTITUTION:A grid extended between a discharge electrode 1 and a photosensitive body 3 is divided into two, namely, G1 and G2, and voltages of 300V and 600V are impressed to the grid G1 and G2, respectively. As for an electrostatic charging device of this constitution, the surface potential of the photosensitive body 3 has two stages, rises up to the potential of the grid G2, a charging current becomes a distribution having two peaks, and a peak value of its current is suppressed low. In a place where the charging current is large, ions flow in large quantities, activated particles increase, and the photosensitive body is deteriorated, but since the peak value of the charging current is low in this way, the ionic wind is weakened and deterioration of the photosensitive body can be prevented.
摘要翻译：目的：通过将静电充电装置的栅格分割为多个栅格来减弱离子风并防止感光体的劣化，并且在感光体的前进方向上施加逐渐变高的各个电压。构成：在放电电极1和感光体3之间延伸的栅格被分成两个，即G1和G2，并且300V和600V的电压分别被施加到栅格G1和G2。对于这种结构的静电充电装置，感光体3的表面电位具有两级，上升到电网G2的电位，充电电流变为具有两个峰的分布，其电流的峰值为抑制低。在充电电流大的地方，离子大量流动，活性粒子增加，感光体劣化，但是由于充电电流的峰值以这种方式低，因此离子风减弱，劣化可以防止感光体。

摘要： PURPOSE:To reproduce a red picture easily with simple control and constitution by using a photosensitive body where a red damping saturation potential is higher than a white damping saturation potential and changing a developing bias voltage and an image exposure illuminance when red color is reproduced. CONSTITUTION:In a photosensitive drum 1, the red damping saturation potential is higher than the white damping saturation potential. When a red picture is copied, a bias voltage lower than that for normal copy is impressed to a grid electrode of a scotron charger 2 from a power source 11, and the suface of the drum is charged electrostatically with a potential Vo2 lower than Vo1. A voltage higher than that for normal copy is impressed to an image exposure lamp 3, and the red picture is illuminated with an exposure illuminance higher than E1. A bias voltage Vb2 lower than that for normal copy is impressed to a developing electrode, and the red original is copied on these conditions.

摘要： PURPOSE:To obtain a safe copying machine wherein a laser light never reaches an original setting surface, by realizing such arrangement that the angle of incidence of the laser light to a filter is different from that of the laser light passed through the film to the filter after reflection on a photoreceptor. CONSTITUTION:Either a slit exposure optical path A and a laser light optical path B slants to the normal of the photoreceptor slightly. Then, a multi-layered interference filter 5 is provided so as to spread over both optical paths A and B set as mentioned above. When theta'>theta, spectral transmissivity shifts to a short- wavelength side and a transmission zone T2 also shifts to the short-wavelength side, so reflected laser light of 780nm from the photoreceptor is not transmitted through the filter 5. When theta'
摘要翻译：目的：为了获得安全的复印机，其中激光不会到达原始设置表面，通过实现这样的布置，使得激光对滤光器的入射角与通过膜的激光的入射角不同于过滤器在感光体上反射后。构成：狭缝曝光光路A和激光光路B均稍微偏向感光体的法线。然后，设置多层干涉滤光器5，以便如上所述设置在两个光路A和B上。当θ'>θ时，光谱透射率转移到短波长侧，透射区T2也移动到短波长侧，所以来自感光体的780nm的反射激光不会透过滤光器5。 θ，另一方面，光谱透射率偏移到长波长侧，并且来自感光体的反射激光不通过滤光器5透射。对于这种情况，调整激光和滤光器5的位置，使得 θ'和θ不同，因此抑制来自感光体的反射激光通过滤光器5，使得激光从未通过狭缝曝光光路A到达原始设定表面。
