PURPOSE:To enable the continuous gradation recording by easily changing the amt. of the molten ink material that is stuck, and transferred by changing an added heat quantity. CONSTITUTION:The ink material layer 120 is heated from the back surface 120b, and generates a molten ink material 140a. The melting propagates to the front surface 120a of the ink material layer by the thermal conductivity through the molten ink material 140a. Meanwhile, as auxiliary particles 123, if its melting point thereof is selected to be one higher than that of a binder material 121, the temperature rising is continuous up to the melting point. After then, the melting heat is supplied by the heating from the surfaces of the auxiliary particles 123a, and 123b that have higher melting points. And the molten ink materials 140b and 140c are generated around the surfaces 123a, 123b, and hence the fluidity is increased. As the molten ink materials 140a and 140b are expanded by thermal expansion, the capillary phenomenon occurs at a narrow gap between the auxiliary particle surface 123b and the recording medium surface 200a, and because of this, the ink material moves along the auxiliary particle surface 123b, to stick and transfer it to a recording medium surface 200a.
