An image forming method having excellent spectral characteristics with sharp absorption, high image fastness, and high transfer density. A thermal transfer image-receiving sheet having a receiving layer containing a polymer selected from polyester and / or polycarbonate-based polymer, vinyl chloride-based polymer, and polymer latex on a support, and an azo represented by the following formula: An image is formed by overlaying a thermal transfer sheet having a thermal transfer layer containing a dye on a support and applying thermal energy from a thermal head. (R 1 to R 4 are hydrogen atoms or substituents; Het represents a heterocyclic group.) [Selection figure] None |
