Abstract: A method and apparatus for regenerating a thermosensitive transfer recording medium 1 comprising a dye layer having a thermally diffusable dye at a concentration, wherein the medium 1 is superposed on a material 10 to be transferred and heated in an imagewise pattern to transfer the dye of the medium 1 to the material 10 to be transferred thereby forming an image. The apparatus comprises a dye supplier 4 containing a thermally diffusable dye at a concentration higher than that of the dye layer, and a heating means 7 for diffusing the dye from the supplier 4 toward the dye layer whereby the dye consumed during the transfer recording operations is supplemented from the supplier 4 to the dye layer. A thermosensitive transfer recording apparatus is also described along with a thermosensitive transfer recording medium and a dye supplier.
