PURPOSE:To expand the selection of image receptor materials and to improve coloring efficiency by arranging image forming particles contg. colorless sublimatable dyes on backing in correspondence to image signals and sublimating the dyes to image receptors then sticking developers to the image receptors. CONSTITUTION:The image forming particles 2 contg. colorless sublimatable dyes 1 are arranged on backing 3 in corresponding to image signals by a method of sticking particles electrostatically on the latent images charged electrostatically according to the image signals by means of an electrostatic pin or the like on a dielectric. After the particles 2 are transferred onto an image receptor 4 by an ordinary method, they are subjected to a sublimation treatment to contain part or the whole of the dyes 1 into the layer of the receptor 4. Further, the particles 2' are cleaned by an ordinary means, then the dyes 1 are colored by a brush 5 impregnated with a soln. contg. a developer, whereby colored images 1' are obtained. Resins such as acrylic resins which do not exhibit acidity are used for the image forming particles. |
