Abstract
In a non-impact recording apparatus comprising (i) a recording head comprising (a) a recording electrode consisting essentially of a plurality of recording styli, and (b) a return electrode, which are embedded in an electrically insulating support member, and (ii) an image-delineating signal application apparatus which applies image-delineating electric current between selected recording styli and the return electrode so as to generate Joule's heat in the portions in an ink ribbon containing an electroconductive thermo-fusible ink material immediately below the recording styli and to soften the ink material, thereby transferring the softened or fused ink material in image patterns to a recording medium, the improvement wherein, on the side of the recording head in contact with the surface of the ink ribbon, there is formed a groove portion out of contact with the surface of the ink ribbon between the recording electrode and the return electrode, thereby preventing the deposition of a layer of the electroconductive ink material between the recording electrode and the return electrode.
