PURPOSE: To raise gasification efficiency and heating efficiency by a method wherein a heating means in which a recording material of a recording material accomodating part is heated to be transferred to a material to be recorded is composed of a heating element which extends at least in a depth direction of the recording material accomodating part. CONSTITUTION: When a head 70 is operated as an actual vaporizer, a molten liquid dye 22 sucked up by a capillary phenomenon from a side surface of a piller-shaped body 175A of a micro-heater is heated at about 50-300 deg.C by the piller-shaped heater part 175A ranging over the whole in a depth direction. The dye 22 is vaporized from an upper part hole 150 of an electrode 85 and around an electrode 84 to be stuck to a material to be recorded, and printing can be carried out on photographic paper without any contact. In that case, the dye 22 permeated around the piller-shaped body 175A can be efficiently heated to be vaporized without fleeing. Further, since the heat is generated by the piller-shaped heating element 175A ranging in a depth direction of a dye accomodating part 87, the heat is held sufficiently over the whole of the dye, and there is hardly any influence caused by diffusion on a base 73. |
