PURPOSE:To enable an analog continuous gradation to be transfer recorded by using a pigmented ink which can not be used in a conventional melting transfer recording system, by limiting the weight part of a particulate ink transfer adjuvant mixed in an ink material. CONSTITUTION:The ink material 120 comprises a binder material 121 and the pigment 122. The melting point of the particulate ink transfer adjuvant 123 is selected to be higher than that of the binder material 121. When an electric current is passed to a heating resistor element 512 of a thermal recording head 150 to generate heat and temperature rise recording is controlled, a thermal transfer layer 130 is heated. According to the heating value, the binder material 121 is melted to form an ink material 140a with the viscosity reduced. In addition, the particulate adjuvant 123 is also heated, and an ink material 140b with the viscosity reduces is formed. The melted ink material 140b, 140a with low viscosity permeates along an embedded surface 123a and an exposed surface 123b of the particle of the adjuvant 123 to the side of the surface 200a of the recording medium 200 as indicated by arrows 150, is transferred onto the medium 200, and is solidified. |
