A thermal printer in which color thermosensitive recording material is used is provided. A thermal head records an image to the recording material by applying heat thereto. One or two photo fixing xenon flash lamps apply electromagnetic rays to the recording material, to fix the image. The electromagnetic rays are emitted in the first and second wavelength ranges, and are ultraviolet or visible. A controller changes over electromagnetic rays received by the recording material from the xenon flash lamps. The controller, when in a first step, sets the electromagnetic rays in the first wavelength range by means of a UV absorbing filter, to fix a first coloring layer for yellow. In a second step next to the first, the electromagnetic rays are set in the second wavelength range, to fix a second coloring layer for magenta.
