Abstract

PURPOSE:To lower running cost while maintaining a printing speed, by a construction wherein a protective layer, a resistance layer, a conductive layer and a base layer are integrated with each other to produce a current-sensitized thermal sheet which is separate from a heat-fusible ink layer. CONSTITUTION:An electrode unit 10 comprises positive and negative electrodes 10-a, 10-b. The current-sensitized thermal sheet 8 comprises the protective layer 1, the resistance layer 12, the conductive layer 3 and the base layer 4. The layer 1 is a vapor-deposited carbon film, the resistance layer 12 is formed of a material prepared by dispersing a small amount of conductive carbon in a polycarbonate, the conductive film is a vapor-deposited aluminum film, and the base layer 4 is a polyethylene terephthalate film. The layer 3, the layer 12 and the layer 1 are sequentially provided on the base layer 4 by vapor deposition or coating. The heat-fusible ink sheet 9 is produced by providing a polyamide layer 6 comprising a coloring material such as carbon black dispersed therein on a polyester film base layer 5 by roll coating. The ink sheet 9 is sandwiched between the thermal sheet 8 and a recording paper 7, and current- sensitized recording is conducted in a single stroke.
