    摘要： In an electrophotographic process for the formation of an electrostatic latent image on a photosensitive element for electrophotography produced through the sequential lamination on an electrically conductive substrate of an electrically insulating layer, a photoconductive layer, and an electrically insulating surface layer by repeating a series of steps comprising a first charging; a light exposure of the entire surface; a second charging of a polarity opposite to that of the first charging; and an image-wise exposure to light, wherein the polarity between the first electrical charging and the second electrical charging is changed from positive to negative and vice versa simultaneously (either a positive image or a negative image can be obtained from an original using the same developer).
