PURPOSE: To provide a thermal transfer sheet having a high sensitivity, a re duced running noise at the time of transfer, and a good gradation reproducibility and preventing misregistration in overlapping colors at the time of forming a multicolor image for realizing a color image of a higher sharpness and an image forming method therefor. CONSTITUTION: A thermal transfer sheet is provided with an ink layer containing 30-70wt.% pigment and 25-65wt.% amorphous organic polymer having a softening point in the temperature range of 40-150 deg.C and ranging 0.2-1.0μm in layer thickness and an adhesive layer formed thereon. An image-receiving sheet is overlapped on the adhesive layer of the thermal transfer sheet. On the back surface of the thermal transfer sheet, a thermal head is pressed, or a laser light modulated by digital signals is emitted (or a laser light modulated by digital signals is emitted in an ablation method). In this manner, a transfer image formed with an area gradation of a 1.0 or more optical reflection density is formed on the image-receiving sheet. |
