Liquid-ejection apparatus

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.
