PROBLEM TO BE SOLVED: To shorten a photofixing time. SOLUTION: A thermal printer 2 comprises a thermal head 6 for recording on a thermal recording material 3, and yellow and magenta photofixing units 9 and 10 performing photofixing after thermal recording. The thermal recording material 3 is a recording material for OHP where thermal coloring layers of yellow, magenta and cyan are formed on a transparent support. The yellow photofixing unit 9 comprises two UV lamps 23a and 23b for Y. One of the lamps 23a and 23b is disposed oppositely to the recording face of the thermal recording material 3 and the other is disposed oppositely to the rear surface. At the time of photofixing, respective lamps 23a and 23b are lighted and the thermal recording material 3 is irradiated with UV-rays on the opposite sides. Similarly to the case of the yellow photofixing unit 9, the thermal recording material 3 is irradiated with UV-rays on the opposite sides by means of two UV lamps 26a and 26b for M in the magenta photofixing unit 10.
