ABSTRACT OF THE DISCLOSURE An thermal transfer printing method which is performed by the use of an thermal printer comprising a platen, a thermal print head having at least one heating element and a length of ink carrier ribbon with the recording medium positioned between the thermal print head and the length of ink carrier ribbon, which ink carrier ribbon having a base film and an ink layer, which method comprises the steps of pressing the ink carrier ribbon against the platen by means of the thermal print head with the ink layer brought in contact with the recording medium, heating the heating element to cause that portion of the ink layer, which is aliened with the heating element, to fuse, and causing that portion of the ink layer so fused to partially transfer onto the recording medium when a cohesive force acting internally of the ink layer becomes smaller than an adhesive force acting between the ink layer and the recording medium and, at the same time, smaller than a adhesive force acting between the ink layer and the base film, whereby the cohesive force is substantially destroyed so as to permit the thickness of the ink layer to be substantially split into halves such that one of the halves is transferred onto the recording medium and the other of the halves remains adhering to the base film.
