ABSTRACT:
A recording method of ink jet system which employs a recording solution composed of a dye which vaporizes more than 90 wt % upon heating at a temperature above 300.degree. C., leaving residues in an amount less than 10 wt %, and a solvent having a boiling point higher than 150.degree. C. which dissolves or disperses the dye more than 5 wt % at a temperature below 50.degree. C., the recording solution being heated at the time of recording by the recording solution heating unit which has a porous structure formed thereon which is composed of fine parts whose dimension in the plane direction is 0.2-3 .mu.m and whose dimension in the direction perpendicular to the plane direction is 2-15 .mu.m. This recording method makes use of the advantage of both the thermal transfer system and the ink jet system. Thus, it realizes a high resolution and a gradation within a picture element, produces high-quality images promptly, permits the printer to be made small and light, involves no waste materials, permits printing on plain paper, and needs a less amount of power and running cost.
