Abstract
A method for recording an image on a thermal recording material in which a plurality of color-development layers are laminated, the plurality of color-development layers being adapted to develop different colors, respectively, upon supply of thermal energy thereto and to form a substantially black color when all of the plurality of color-development layers undergo color development with a substantially identical density. With respect to a portion where a color other than black is to be developed, recording is effected such that a color-development density of each of the plurality of color-development layers becomes lower than a maximum color-development density of each of the plurality of color-development layers. Meanwhile, with respect to a portion where black is to be developed, recording is effected such that the color-development density of each of the plurality of color-development layers becomes higher than a maximum value of color-development density of a portion surrounding the portion where black is to be developed. Accordingly, the density of black becomes higher than the densities of colors other than black, so that a sharp contrast is produced in the black color of the image recorded on the recording material.
