PURPOSE:To make plain paper usable for a recording medium, by charging reversely the respective photosensitive layers of a photoreceptor consisting of two kinds of photosensitive layers differing in sensitivity to white, charging electrostatically mixed systems of 3 kinds of filter particles contg. sublimable dyes and subjecting the photoreceptor to exposure, fixing, etc. CONSTITUTION:The respective photosensitive layers of a photoreceptor 1 produced by laminating two layers of photosensitive layers differing in sensitivity to white are charged in respectively reverse directions, and mixed systems of 3 kinds of filter particles contg. sublimable dyes are electrostatically charged to a prescribed polarity and are stuck on the one layer, then the photoreceptor is subjected to exposure of a color image. The electrostatic latent image part corresponding to the black image on the photoreceptor 1 is developed with a black toner TBW after the image exposure. A colorless or a white toner TW incorporating an electron acceptive material is stuck on the remaining filter particles and these toners and filter particles are transferred onto plain paper S. The dyes are then sublimated and the toners colored and are fixed. The plain paper is thus made usable for the recording medium. |
