ABSTRACT:
A heat-sensitive transfer image forming method, containing: superposing receptor layer side of image-receiving sheet and dye layer side of ink sheet, making a thermal head contact with the sheets from lubricating layer side of ink sheet, and applying heat while making the head and ink sheet move at 60 mm/s or more relatively, and thereby transferring dye to form an image; wherein image-receiving sheet has heat insulation layer containing hollow polymer particles, receptor layer and/or heat insulation layer contains a water-soluble polymer; lubricating layer contains inorganic particles in 0.01-5 mass % to the total solid content of lubricating layer, the particles have Mohs' hardness 3-6 and mean particle size 0.3-5 μm, and the ratio of the maximum width of each particles to the sphere equivalent diameter thereof is 1.5-50; and when 0.7 J/cm2energy is applied, contact distance between the head and lubricating layer is 350-450 μm.
