PURPOSE: To improve transfer sensitivity by facilitating volatilization of a recording material, by a method wherein at least two kinds of recording materials (transfer dyes) are allowed to mixe up with each other at a fixed mole fraction and when steam pressure is specific at a fixed temperature, a specific formula is satisfied in a specific temperature sphere.
CONSTITUTION: In a head part (recording part) 10, solid sublimating dyes 12 within a holding tank 11 is melted by a heater 16, the liquid sublimating dyes 12' are supplied to glass beads 22 of an evaporation part 17 by making use of a capillarity of a liquid dye holding tank 15. Laser beams L generated by semiconductor laser chip 18 is converted into heat by a beam and heat converting body 21, the liquid sublimating dyes 12' are evaporated and transferred to an image receiving layer 50a of the recorded paper 50. On this occasion, at least two kinds of recording material (transfer dyes) are allowed to mix up with each other at a fixed mole fraction and when steam pressure is Pmix at a temperature T, the following formula is satisfied within a temperature sphere of 25-500°C. Namely, the formula is: Pmix>ΣPK.xK. Wherein PK, xK are respectively the steam pressure and mole fraction of the Kth recording material at the temperature T.
