ABSTRACT:
An improved thermal recording head having a large number of heating elements connected in parallel between a plurality of pairs of electrodes for recording halftone images is provided. Each of the heating elements has end portions divided into two leg sections, and the center portion is narrowed. This configuration allows the thermal recording head to reduce image-roughness to the naked eye. In addition, the variable range of recording density can be significantly expanded.
