Abstract

PURPOSE:To control coloring areas by controlling the time width of the current to be flowed to the heating resistor formed integrally with a heat conductor. CONSTITUTION:If the time width of the current to be flowed to the heating resistor 1 opposing to one picture element formed integrally with the heat conductor 2 provided on both side, the heat evolved by the resistor 1 heats the heat conductor 2, causing the temperature distribution in one picture element to change. Thereby, the coloring area is controlled and the heat-sensitive recording of high quality of intermediate tone may be accomplished with stability and high gradation.
