ABSTRACT:
A thermal head for transferring heat-sensitive ink material coated on an ink support onto a recording sheet comprises heating elements capable of coming in pressure contact with the support for heating a transfer part of the ink support. A pressing protrusion then presses the heated transfer part of the ink support onto the recording sheet with a pressing force larger than that exerted during the pressure contact with the heating elements. A base plate holds the heating elements and the pressing protrusion such that the pressing protrusion is disposed on the base plate spaced apart from the heating elements. The pressing protrusion protrudes higher from the base plate than does the heating elements.
