摘要： In practicing multi-step reproduction of color image by electrophotography using an electrophotographic photosensitive material prepared by overlaying a photosensitive layer composed mainly of titanium dioxide and a binder on an electroconductive substrate, exposure to an optical image is first carried out, then positive corona charging is carried out to form a positive electrostatic latent image and subsequently developing is carried out. Further, prior to the exposure to an optical image, negative corona charging and/or AC corona charging are additionally carried out. By this electrophotographic process effectively utilizing the photomemory effect of titanium dioxide, multi-color images can be produced, and an image having good contrast can be reproduced easily and stably.

摘要： A liquid developing apparatus for developing a latent electrostatic image by contacting a liquid developer with an electrophotographic photoreceptor bearing said latent electrostatic image on the undersurface thereof while moving the electrophotographic photoreceptor horizontally over a liquid developing bath. In the apparatus, a number of horizontally spaced developing electrodes in the form of bars having a vertical cross-section in the shape of a tetragon are disposed in the bath very near the undersurface of the photoreceptor. When the liquid developing apparatus is used, an electrophotographic image can be obtained having a high quality but being free from non-uniformity of image density, edge effect and flow of image or streaks.
