ABSTRACT:
An ink jet recording method for recording in which an ink is discharged by the pressure of a bubble generated in the ink by means of thermal energy, having the steps of preparing an ink jet head having a liquid path provided with a heating element and communicated with a discharge opening supplying the ink into the liquid path, the ink having a surface tension equal to or less than critical surface tension of a recording medium generating thermal energy for generating a bubble with the heating element in such a manner that the bubble is communicated with the atmosphere from the discharge opening when the generated bubble has a negative internal pressure and discharging the ink from the discharge opening by means of the pressure of the bubble generated.
