ABSTRACT:
A thermosensitive recording medium is preheated to a temperature beyond which the thermosensitive recording medium produces color by a heat roller which is held in contact with the thermosensitive recording medium. Then, thermal energy according to an image to be recorded is applied to the preheated thermosensitive recording medium by a thermal head, thereby recording a gradation image on the thermosensitive recording medium. Thereafter, the thermosensitive recording medium is heated again, substantially uniformly over the entire surface thereof, by a heat source for stabilizing the color density of the recorded image.
