A recording signal is applied to the recording head 1 while pressing the ink sheet 4 and the receiving paper 7 in between. The heating resistor element 3 generates heat due to the application of the recording signal, and the generated heat is transmitted through the base film 5 of the ink sheet 4 and raises the temperature of the thermal sublimation dye Ns6. An amount of dye corresponding to the heating temperature and time is sublimated from the thermal sublimation dye layer 6 and dyed onto the receiving paper 7 to form an image 9.
