ABSTRACT:
Disclosed is a color electrophotographic method of forming a plurality of images of different colors on a photosensitive medium by repetitions of a series of operations including steps for charging, exposure and development. An exposure of photosensitive medium is conducted to form an electrostatic latent image adjacent to a first toner image which has been formed in the previous process with a non-image are provided at the boundary of the first toner image. The difference in potentials between the toner image and the adjacent image is thereby eliminated, thus preventing scattering of toner particles. This results in a clear color print the colors of which are not blurred and of high purity.
