    • There is disclosed an electrophotographic process adapted for using a cylindrical photosensitive member of a small diameter of 40 mm or less which has such a charging characteristic that when it is charged to 700 V (or -700 V) and then exposed to such an intensity of light as to provide a potential of 200 V (or -200 V) after exposure for 50 msec., the photosensitive member will have a potential of 20 to 150 V (or -20 to -150 V) after exposure for 150 msec. In the process, the steps of charging, exposure, developing and transfer involved, and the following relationship is satisfied: R.theta./v.gtoreq.0.30, wherein R (mm) is the outer diameter of the cylindrical photosensitive member, .theta. (radian) is the angle formed between the exposure and the developing position on the cylindrical photosensitive member with respect to the center thereof as the angle center, and v (mm/sec) is the circumferential speed of the cylindrical photosensitive member. By the process, undesirable increase in residual potential on the photosensitive member to solve the problems of increasing image density and fog during successive copying.
    • 公开了一种电子照相方法,其适用于使用小直径为40mm或更小的圆柱形感光构件,其具有这样的带电特性,即当其充电至700V(或 - 700V)时,然后暴露于这样的强度 光在暴露50毫秒后提供200V(或-200V)的电位,感光构件在曝光150ms后将具有20至150V(或-20至-150V)的电位。 在此过程中,满足充电,曝光,显影和转印的步骤以及以下关系:Rθ/v>/=0.30,其中R(mm)是圆柱形感光件的外径,theta(弧度 )是圆筒状感光体上的曝光与显影位置之间的角度,以圆心为中心,v(mm / sec)为筒状感光体的圆周速度。 通过该过程,感光构件上的残留电位的不期望的增加以解决在连续复制期间增加图像浓度和雾的问题。
