PURPOSE:To enable high-speed printing and high-resolution, by performing energization while moving a recording needle and a heat generating plate relative to each other, and thermally transferring a thermal transfer layer by the heat generated by an electrically energized heat generating layer and a conductive layer or by the electrically energized heat generating layer and a conductive base layer. CONSTITUTION:Heat generating plate is laid on the surface of a conductive layer of a recording material comprising a thin metallic film having a surface resistance of less than 50 OMEGA, or on the surface of a conductive base layer of a recording material comprising a thermal transfer layer on one side of the conductive base layer comprising a metallic foil having a surface resistance of less than 1OMEGA and a thickness of 2-30 mum. The heat generating plate comprises an electrically energized heat generating layer having a surface resistance of 10-10<7>OMEGA provided on one side of an electrically anisotropic plate-shaped body in which a multiplicity of acicular bodies of a conductive ceramic having a volume resistance of not more than 10<-1> OMEGA-cm are dispersed in a matrix of a non-conductive ceramic having a volume resistance of at least 10<6> OMEGA-cm. Energization is conducted while moving an electrothermal recording needle placed in contact with the other side of the plate-shaped body and the heat generating plate relative to each other, and a thermal transfer layer is thermally transferred by the heat generated by the heat generating layer and the conductive layer or by the heat generating layer and the conductive base layer. |
