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 prevent an effect of ozone on a photosensitive body and to stabilize an electrophotographic image by controlling ozone concn. in an atm. surrounding said body having a photoconductive layer contg. a phthalocyanine type pigment to a prescribed value or less. CONSTITUTION:A photosensitive drum 2 provided with a photoconductive layer contg. phthalocyanine type pigment on the surface is installed in the main body 1 of a copying machine. Ozone concn. in an atm. surrounding the drum 2 is detected with a gas sensor 28 using phthalocyanine as its element material, and when it is over a prescribed value, the corona current of a scorotron type electrostatic charger 3 is lowered to within a prescribed value. As a result, generation of ozone due to action of the charger 3 is suppressed to control the ozone concn. in an atm. of the drum 2 to a prescribed value or less, and adverse effect of ozone on the drum 2 is thus prevented.

摘要： PURPOSE:To stabilize an electrophotographic picture by controlling an ozone concentration in a photosensitive body portion atmosphere to a prescribed value or below. CONSTITUTION:A photosensitive drum 2 having a photoconductive layer containing a phthalocyanine compound pigment on the surface is provided in a copying machine body 1 so as to be driven to rotate counterclockwise. A gas detector 24 whose element material is the same phthalocyanine as that of the drum 2 is placed in the vicinity of an electrostatic charger 3 and in the vicinity of transfer and separation chargers 5, 6, in which ozone is generated easily, to detect ozone density in an atmosphere of the drum 2. When the detected ozone concentration is above a prescribed value at the standby for the copying, an exhaust for 26 directly doupled with a main motor 25 or an exhaust fan 27 of a carrying belt 20, etc. are operated, air in the body 1 is exhausted or attracted to eliminate, and the ozone concentration in the atmosphere of the drum 2 is reduced to a prescribed value or below. Accordingly, it is unnecessary to provide newly a special ozone diluting means.

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。
