Abstract

PURPOSE:To heat a heat sensitive recording paper indirectly, thus preventing local overheat resulting elimination of blurs by contacting a specially constituted heat generating sheet to a heat sensitive recording paper, and by providing a recording electrode and an opposite electrode. CONSTITUTION:A substance such as an electroconductive polymer is painted to form a heat generating layer 4a on one side of a protective layer 4b such as a Tetoron film, thus obtaining a heat generating sheet 4 with a thickness of, for instance, 100mu or less. The protective layer 4b side of the sheet 4 is brought into contact with the surface of a heat sensitive recording paper 1; and to the other side or heat generating layer 4a side, a probe type recording electrode 5 and an opposite electrode 6 that has a large cross-sectional area are placed at corresponding positions with a distance of d. When the power source B is applied between the both electrodes 5 and 6, the current flows from the electrode 5 through the heat generating layer 4a to the electrode 6. As a result, an area corresponding to the distance d is locally heated, and the heat is transfered to the recording paper, thus coloring the paper due to the heat. USE:Facsimile, printer, and others.
