ABSTRACT:
A thermal printer which uses a thermally transferably ink sheet having an irregular surface comprises heating means for generating heat in response to an input signal applied thereto; first support means for movably supporting a recording sheet and providing a pressure on the recording sheet in a direction toward the heating means; second support means for movably supporting a thermal transfer sheet in contact with the heating means, the thermal transfer sheet comprising a heat resistive base and a thermally transferably ink layer on one side of the base, the layer comprising a mixture of a coloring agent and a hot melt binder, the mixture being transferably to the recording sheet in response to application of heat to the other side of the base, and auxiliary particles distributed in the layer so that they partially emerge from the surface of the layer; means for moving the first and second supporting means; and means located down stream with respect to the heating means for separating the transfer and recording sheets from each other before the heat mixture solidifies.
