A reversible thermal recording material permits recording having a clear contrast at a high sensitivity and erasing such images a number of times, at least 1,000 times, repetitively, and comprises a leuco dye, a reversible developer and a light-heat-converting dye, the light-heat-converting dye having a deterioration ratio of 20% or less when a laser beam having an oscillation wavelength of 830 nm is applied thereto repeatedly 1000 times at a temperature of 25° C. at an energy of 2 J/cm2 or being a phthalocyanine compound having a vanadyl group, and a method of recording an image comprises applying a laser beam to the reversible thermal recording material, wherein the colored leuco dye is achromatized with energy that is 25 to 65% of the energy of the laser beam employed for causing the leuco dye to develop a color.
