PURPOSE: To improve efficiency in gasification by transmitting heat efficiently to a recording material by a method wherein a porous structure which holds and feeds the recording material is provided at a position deeper than that of a heating element provided on a surface area of the recording material. CONSTITUTION: A heating element 75 is arranged on a surface area of a liquified dye 22 in a dye-accomodating part 87 of a printer head 70. Therefore, temperature of the liquified gas 22 is quickly raised on the surface area to make thermal efficiency by heating ascend, and efficiency in transfer of the dye by gasification can be improved. Further, a fine meandering pillar-shaped body 80 for holding and feeding the dye 22 is provided as a porous structure at a position deeper than that of the heating element 75 on the surface area of the dye 22 in contact therewith. Therefore, a capillary structure comes to be provided also to a gasification part 77, running away of the dye is inhibited by capillary action to hold the dye effectively and feed a specific amount thereof, and heat by the heating element 75 can be efficiently transmitted. |
