PURPOSE:To enable recording to be performed at a high speed, by a method wherein a photoabsorption layer is established on a transparent substrate, said photoabsorption layer is irradiated by focussed light beams to increase its temperature, ink is gasified by heat energy of an increased temperature part, and an ink drop is flown by pressure in said gasification time to perform printing. CONSTITUTION:Focussed light beam 23 penetrate a transparent substrate 22 to irradiate a photoabsorption layer 21, and the irradiated part is increased in temperature to become a heating part 12. In this case, when ink 9 in contact with the heating part 12 causes film boiling to come to be in a bubble 10 state, and a bubble 10 is generated in a frame structure 28, pressure is generated in the arrow A direction, and ink 9 becomes a liquid drop 11 via a nozzle hole 13. The liquid drop 11 is separated from the ink 9 by suction acting when the bubble 10 disappears and flies to record on recording paper. A recording speed of an obtained bubble jet printer becomes high. |
