ABSTRACT:
Electrophotographic copying apparatus of this invention includes an electrophotographic photosensitive member, elements for forming an electrostatic latent image on the photosensitive member, and for liquid developing the latent image, and elements for removing an excess liquid developer after the development and for applying thereafter substantially uniformly an electric field on the surface of the photosensitive member with the aid, for example, of a corona discharger or an electrode. The developed image is then transferred onto a transfer material and the photosensitive member is cleaned after the transfer, wherein each of these last two functions may be accomplished by conventional elements.
