COLOR MAGNETIC MICROCAPSULE TONER AND COLOR IMAGE RECORDING METHOD USING SAID TONER

摘要

PURPOSE:To obtain a sharp color image by using a color magnetic microcapsule toner contg. a heat sublimating dye and executing image recording by heat fixing. CONSTITUTION:The color magnetic microcapsule toner is formed by providing the 1st film wall of a thermoplastic resin contg. the heat sublimating dye on the outside of each microglass sphere and providing the 2nd film wall of a porous heat resistant resin contg. magnetic powder thereon. A photosensitive drum 1 is electrostatically charged over the entire surface by a corona discharger 2 and a latent image is formed thereon by an exposing device 3. The toner image is developed by developing machines 4a-4d and is transferred to plain paper by a transfer device 7. The transferred toner is heated by a heat roll 9 for fixing and the heat sublimating dye is sublimated and fixed onto the plain paper 6. The residual toner remaining on the paper 6 is removed by a cleaning brush 10 and the sharp color image is recorded on the plain paper. The toner particles remaining on the photosensitive drum are removed by a cleaning brush 8.
