Abstract
A plurality of pattern electrodes which are disposed in correspondence with the printing dots are provided on one surface of a substrate biased in one direction. An anisotropic electroconductive element is supported to enable its release on the substrate which has a first turn-on surface contacting the pattern electrodes on its substrate, and a second turn-on surface contacting the electroconductive transfer sheet and exhibiting excellent conductivity between only its first and second turn-on surfaces. In the printing action, electric conduction is achieved on a transfer sheet depending on the printing pattern from the pattern electrodes through the anisotropic element, so that the resistance layer of the sheet may emit heat, thereby the ink contained within the ink layer of the sheet is melted for printing.
