PURPOSE:To eliminate recording density irregularity generated by surface unevenness, by providing the shape memory alloy, in which a shape was stored, protruded to the side of a recording medium to the back side of a heat generating resistor to enhance the contact property of said resistor with recording paper. CONSTITUTION:A shape memory alloy 8 is provided on a substrate 9 comprising an elastomater but under the part where a heat generating resistor must be provided. An insulating layer 7, a heat insulating layer 6 and a heat generating resistor 3 are laminated onto the upper side of said alloy 8 and a protective layer 5 is provided as an uppermost layer. When this shape memory alloy 8 is heated, the pat of the heat generating resistor 3 is protruded to the side of a recording medium. The recording to heat-sensitive paper is performed by applying a current to the heat generating resistor to heat the same to predetermined recording temp. and contacting said resistor with the heat-sensitive paper. At this time, the shape memory alloy 8 is heated and deformed to a stored shape. The substrate 9 comprising the elastomer is deformed along the movement of the shape memory ally 8 and the heat generating resistor is protruded toward the recording medium. Therefore, even if the recording medium has slight unevenness, the heat generated part is certainly contacted with the recording medium and recording with desired concn. can be performed. |
