Abstract
An ink jet recording device in which an ink carrier film is formed to have a plurality of pores or recesses, the pores or recesses are filled with ink, the film filled at their pores or recesses with the ink is quickly heated by such a heat supply source as a thermal head according to picture image information to generate bubbles within the ink in the heated pores or recesses and to eject the ink onto a recording medium under influence of the pressure of the bubbles for recording. The ink carrier film comprises at least two layers one of which on a side of the heat supply source is made of a heat-insulating, low-friction material, thus improving the thermal efficiency of the ink carrier film and minimizing the frictional wear of the heat supply source.
