Abstract

A liquid ejecting method using a liquid ejecting head having electrothermal transducer elements for generating thermal energy sufficient to create bubbles in liquid and ejection outlets disposed opposed to the electrothermal transducer elements which are arranged at a density not less than 300 per 25.4mm in a line, the liquid ejection head also having liquid flow paths in fluid communication with the ejection outlets, respectively, wherein the bubble generated by the thermal energy generated by the electrothermal transducer element is brought into communication with ambience while an internal pressure of the bubble is less than an ambient pressure, and wherein droplets having volumes not more than 15x10-15m3 are ejected at a frequency not less than 7kHz, said method includes the improvement wherein the liquid flow path of the liquid ejecting head has a height not less than 6µm, and a distance between an upper surface and a lower surface of the ejection outlet is not more than one half of a minimum opening distance through a center of the ejection outlet.
