PURPOSE:To provide an ink drop jet recording method and a record head, in which bubbles are formed in stable manner and burst in the outside air to produce ink drops so as to form images having high image quality. CONSTITUTION:A heat energy supply means 2 and a discharge outlet 5 arranged in a position opposite thereto for discharging a part of liquid are provided. A distance L between the heat energy supply means 2 and the discharge outlet 5 and the maximum opening diameter R of the discharge outlet satisfy R/L>=0.4. When ink drops are to be discharged by making bubbles burst in the outside air, uniform bubbles are formed without using complicated structure, so that the burst of bubbles in the outside air is stabilized. Accordingly, recording with high frequency will be achieved and images having stabilized image quality can be obtained. |
