Abstract
PURPOSE: To obtain a clear, bright positive color image, by exposing negative colors on the layer of coloring transparent particle groups of three primary colors electrostatically deposited on the surface of electrophotographic photoreceptor, remaining only desired particles, and transferring the particle images on transparent image receptor.
CONSTITUTION: As a transparent image receptor, a plastic transparent film such as cellulose acetate, or glass plate is used. Mixtures 6 of nonsensitive conductive coloring particles colored in each color of the three primary colors by additive process are electrostatically deposited on the surface of an electrophotographic photoreceptor 3 charged in dark place, and are arrayed almost in one layer. After exposing the image through a color negative film 7, the image is developed by removing particles of which electrostatic attraction to the photoreceptor is weakened by exposure, and the particle images of the remaining coloring particles are transferred on a transparent image receptor 9. White light is radiated from the back of the image receptor 9 after transferring, and the scattered light from the particles is observed from the transmitted side of the white light, so that an inverted color image may be observed.
