PROBLEM TO BE SOLVED: To apply double-color recording capable of suppressing the blur of colors and good in the separation capacity of a pluraity of colors to a double- color thermal recording medium changed in its developed color state by heating temp. SOLUTION: Red and black recording images are read from an image memory 9 and recording image data are synthesized according to a predetermined rule and fundamental recording energy is calculated corresponding to whether the noticeable pixel within the reference region extracted in a reference region extraction part 14 is a red or black recording image by a recording energy control part 15. Further, in a heat control part 16, the fundamental recording energy of the noticeable pixel is corrected on reference to the heat control data stored in a heat control data ROM 17 to form recording data. In a recording drive part 18, a drive current supply pulse signal for controlling the driving of a recording part 19 is formed on the basis of the recording data to drive the recording part 19 to perform the simultaneous printing of red and black colors. |
