ABSTRACT:
An electrophotographic method for color image formation, wherein use is made of an electrophotographic photosensitive member having a multitude of isolated electrically conductive members for forming image elements, a photoconductive layer, and a multitude of sets of electrodes for determining an electric potential of the isolated electrically conductive members in correspondence to a color image original, each set of electrodes comprising a non-transparent electrode, a transparent electrode, and color filter electrodes, and wherein a voltage is applied across the electrodes followed by development.
