Field of the Invention The present invention relates to an image forming apparatus, and more particularly to an image forming apparatus using a thermal sublimation technique and a thermal sublimation type printer using the same. • [Prior Art] - Thermal imaging technology is widely used in photo printing. Its general working principle is: Dry solid ink on the ribbon, that is, a mixture of toner and polymer, which is thinly coated. The belt is divided into yellow, cyan 'magenta three, slightly larger than the size of the photographic paper. When printing, the photographic paper and the ribbon pass through a printing roller at the same time and are heated under the printing head. The single crystal stone with a diameter less than 40 mm on the printing head is energized and applied to the ribbon. The dry solid ink melts. During the heating process, the polymer molecules are separated by a force of about 32 Fahrenheit. As the print head passes, the temperature drops and the ink changes from a gaseous state to an ink-embedded polymer. The polymer molecules are polymerized at the same time.
