    摘要： This invention is a method of color electrophotography in which toner images are superposed sequentially on a photosensitive material sheet to form a multi-color image by using a liquid developer. According to this method, the photosensitive material sheet is made to pass by a conductive doctor member and then by an air blasting member in sequence immediately after development, so as to form the multi-color image. By this method, the multi-color image can be formed in the condition that most of a excess developer is removed while a small quantity of carrier liquid containing no residual toner particles is made to exist as a uniform liquid layer on the surface of the photosensitive material sheet, and thus a clear image free from a fogging of the surface can be obtained.

    摘要翻译： 本发明是彩色电子照相术的方法，其中调色剂图像依次叠加在感光材料片上，以通过使用液体显影剂形成多色图像。 根据该方法，感光材料片通过导电性刮板构件，然后在显影后立即依次通过喷砂构件，从而形成多色图像。 通过这种方法，多色图像可以在除去大部分过量显影剂的条件下形成，而少量的不含残留调色剂颗粒的载体液体作为均匀的液体层存在于感光体的表面上 因此可以获得没有表面起雾的清晰图像。

    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.
