Abstract:
1. An image forming method comprising the steps of: (a) forming an image on a thermal transfer sheet of a thermal transfer recording material, and (b) transferring the image onto an image receiving sheet of the thermal transfer recording material, wherein the thermal transfer sheet comprising a substrate having thereon a yellow ink layer containing a thermally transferable yellow dye, a magenta ink layer containing a thermally transferable magenta dye, and a cyan ink layer containing a thermally transferable cyan dye, the image receiving sheet comprising a substrate having thereon a thermally transferable dye receiving layer containing a dye fixing agent; at least one of the thermally transferable dyes is reactive with the dye fixing agent, and satisfies Formula (1): wherein Am is an absorbance at a wavelength of an absorption maximum (λmax a printing rate of each of the yellow ink layer, the magenta ink layer and the cyan ink layer is not more than 2.5 msec. /line; and wherein one of the thermally transferable cyan dyes is reactive with a dye fixing agent, and satisfies Formula (1).
