Abstract
PURPOSE:To enable high-accuracy and high-speed printing to be performed with low electric power, by providing a substrate and a glaze layer provided on the substrate, and incorporating a porous glass powder and gel form porous silica into the glaze layer. CONSTITUTION:A glaze layer 12 comprising a porous glass powder 13 and gel form porous silica has excellent heat resistance and a low thermal conductivity. The glaze layer 12 has a high heat-insulating property because of the lower thermal conductivity, so that by only applying low electric power to a heat generating part, the surface temperature of the layer 12 can be brought to a predetermined temperature necessary for printing. The lower thermal conductivity of the glaze layer 12 enables a corresponding reduction in the thickness of the layer 12 while maintaining a sufficiently favorable heat-insulating property. Therefore, it is possible to reduce the heat capacity of the glaze layer 12 itself, whereby heat can be absorbed into the substrate 11 sufficiently rapidly after printing, which provide the function of rapidly lowering the surface temperature.
