PURPOSE:To enhance the resolution, gradation, and color reproducibility, by blending more than two colorless subliming dyes to be mixed in the molecular form before sticking to the recording body. CONSTITUTION:Colorless subliming dyes to be turned into magenta, cyan, and yellow, which are separately kept in containers 1a to 1c, are heated by a heating device 2 to be gasified. Electromagnetic shutters 4 provided in the injection route of each container are operated by the signals from a color signal source 3, and the dye gases are controlled of the injection quantity and are mixed in an injection nozzle 5. Next, image signals are applied from an image signal source 8 into the space between an electrode 6 and an accelerating electrode 7 provided in the nozzle 5, and the injection quantity of the mixed gas is controlled. The injected gas flies towards a back electrode 13, and, in the midway when passing through a gas atmosphere 11 of substance 10 obtained by heating of subliming electron acceptor substance 10 in an injection container 9, makes contact with the substance 10 to develop color, thereby sticking to a recording body 12. |
