ABSTRACT:
An electro-thermosensitive transfer printer is provided with a gravure endless ribbon including a conductive thin film belt having a large number of gravure cells on its right side and an electric resistor layer laminated on its back side; and a resistive ribbon thermal print head including an electric insulating plate body coming into contact with the surface of the electric resistor layer, a heat-radiating plate embedded in the plate body, sliding along the surface of the electric resistor layer, and a large number of signal electrodes embedded in the plate body, sliding along the surface of the electric resistor layer. The signal electrodes are arrayed so that each of them is opposite to each of the gravure cells.
