PURPOSE:To obtain image recording of good quality having a clear contour without color irregularity or the like, by a method wherein a photomask plate is prepared to a thermal sensitive information recording medium, and exposure of the photosensitive recording medium is promoted under a state wherein a coloring density of the mask plate is stabilized. CONSTITUTION:If red image information is inputted to a thermal head 1, a platen roller 2 is simultaneously rotated by drive of a motor 5, and information is recorded on a thermal sensitive paper F surface based on red image information, and a photomask plate for the red image is prepared. Herein, a light source 17 is lighted under a state wherein a light source unit 4 is set to a red filter 19a and besides, the light source unit 4 is moved so as to return backward by reverse rotary drive of the motor 5. Thereby, a surface of photosensitive pressure sensitive paper 7 is exposed via the photomask plate for the red image. When exposure is completed thus based on red image information, an optical image is repeatedly recorded on the surface of the photosensitive pressure sensitive paper successively based on green image information and further, based on blue image information. A required visible image can be obtained by crushing an uncured microcapsule. |
