ABSTRACT:
The present invention concerns a thermal recording apparatus, preferably an ink jet thermal recording device and, a process for forming the same and, accomplishes uniformized heat energy action of the heat acting surface (a protective layer surface when there is protective layer), namely the heat-generating resistors of a plurality of electrothermal transducers. The present invention has uniformized the amount of heat energy generated during recording at the heat acting portions by positively changing the shape or the thickness of the resistors concerned with the heat acing portions or/and the constitution itself of the protective layer depending on its existing position.
