Abstract
A color thermosensitive recording material includes a support and yellow, magenta and cyan thermosensitive coloring layers formed on the support. The three coloring layers are different in thermal sensitivity. The yellow coloring layer is the farthest from the support and having fixability to ultraviolet rays of a first wavelength range. The magenta coloring layer has fixability to ultraviolet rays of a second wavelength range. To print a full-color image, the recording material is conveyed alternately in advancing and returning directions. In conveying the recording material in the advancing direction for three times, yellow, magenta and cyan images are recorded respectively to the three coloring layers inside a recording area on the recording material by use of a thermal head. A fixer is operated, which selectively applies ultraviolet rays of the first and second wavelength ranges to the recording material being moved past a ray applying region in a printing path, to fix the magenta and cyan color images. While a border between the recording area and a non-recording area is moved past the ray applying region, a shutter is moved together with the recording material, to avoid fixing the magenta and yellow coloring layers in the non-recording area.
