PURPOSE: To realize the recording of a multicolor image within a short time and to form a multicolor image of high quality generating no color bleeding. CONSTITUTION: A thermal recording material S having a thermal layer containing a color former of a specific color and microcapsules including a photothermal conversion agent absorbing laser beams Ly, Lm, Lc having specific wavelengths to convert them to heat energy is preheated to temp. immediately before color development by a heating roll 22 and subsequently irradiated with a plurality of laser beams Ly, Lm, Lc having specific wavelengths different from each other and modulated corresponding to recording data at the same time to collectively heat the microcapsules corresponding to respective colors to efficiently allow the thermal recording material S to develop desired colors in desired density. |
