PURPOSE:To obtain a high speed and high quality thermal transfer recording apparatus independently of the surface configuration of a receiving article, by differentiating the physical property value at the time of cooling at certain temp. from that at a heating time of ink activated by thermal stimulation. CONSTITUTION:As ink 11, one has a supercooling characteristic is used and, when said ink is heated from ambient temper., the viscosity thereof is lowered as shown by a curve 50 to generate phase transition from a solid phase to a liquid phase but, even if the ink 11 is cooled to ambient temp. thereafter, the ink 11 holds a liquid phase for a certain time as shown by a curve 51. Because the ink 11 has the above mentioned supercooling characteristic, said ink 11 holds melt viscosity even if the ink is left for a long time from a heating process to a transfer process and cooled to the vicinity of ambient temp. and, therefore, by pressing the ink by a transfer blade 46, the transfer to receiving paper 12 is enabled. However, if the variation in room temp. generates, the temp. of the ink at the time of transfer also changes and transfer optimum viscosity is not stably kept and, therefore, the ink is appropriately heated through the transfer blade 46 heated and controlled by the electric heater 56 and temp. sensor 57 provided on the back surface of the transfer blade. |
