PURPOSE:To obtain a high-purity color imge without photographic fog, by giving a pair of parallel faces to light-transmissive image forming particles which contain an image forming sublimatable dye and have the color separating function, and are not fixed to an image forming part. CONSTITUTION:Image forming particles 9 and 10 contain a sublimatable dye and have a color separating function and have a pair of parallel faces at least. Light- transmissive image forming particles are stuck electrostatically to a photoconductive supporting material 1 in one layer, and an image is exposed, and particles whose electrostatic attarction to the supporting material is weakened are removed, and a transfer paper containing an electron receptive material which develops the sublimatable dye is brought closely into contact with the surface of the supporting material and is heted to obtain a colored image due to the dye on the transfer paper. Particles are removed from the transfer paper after sublimating the dye and are not fixed to the image forming part. Since parallel faces of particles 10 are brought into contact with the supporting material 1 on a face, the irregular reflected light and the scattering light are difficult to be incident to the contacting face. |
