摘要： In a method and an apparatus for ejecting liquid, the processing accuracy of an ejection unit for ejecting ink can be easily increased and the variations in the volume of ink drops, the ejection angle thereof, etc., can be reduced even when dust is mixed in ink. In addition, a reduction in an ink-supply speed at which ink is supplied to an ink ejection unit can be prevented. An ink ejection apparatus includes a plurality of heating units (13) provided on a base member (11), ink cells for pressurizing ink with energy generated by the heating units (13), and nozzles (17) having ejection holes for ejecting the ink which is pressurized in the ink cells. Each of the nozzles (17) is disposed above each of the heating units (13). In addition, first open sides of the nozzles (17) which face the heating units (13) serve as ink inlets (17b) and second open sides of the nozzles (17) serve as the ejection holes (17a), so that inner spaces of the nozzles (17) serve as the ink cells, the ink cells not being provided separately.

摘要： Flying characteristics of ink droplets are controlled efficiently to the utmost. In one liquid chamber, two heating elements with the same surface-shape and the same heating characteristics are juxtaposed. While energy is simultaneously applied to the two heating elements, by applying energy with different energy surface-densities to the two heating elements so that the bubble-generating time with film boiling differs for the two heating elements, the liquid droplets are controlled so that a flying force with a component parallel to an ejection face of a nozzle is applied to the liquid droplets in a growing process of the liquid droplets.
