Abstract
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 () provided on a base member (), ink cells for pressurizing ink with energy generated by the heating units (), and nozzles () having ejection holes for ejecting the ink which is pressurized in the ink cells. Each of the nozzles () is disposed above each of the heating units (). In addition, first open sides of the nozzles () which face the heating units () serve as ink inlets () and second open sides of the nozzles () serve as the ejection holes (), so that inner spaces of the nozzles () serve as the ink cells, the ink cells not being provided separately.
