ABSTRACT:
The liquid ejection apparatus includes: a nozzle plate in which a nozzle is formed; a substrate which is opposite to the nozzle plate and is provided with a heat generating element; a bubble generation chamber which has an internal diameter greater than an internal diameter of the nozzle, at a boundary between the bubble generation chamber and the nozzle plate; a liquid storage chamber which stores liquid to be supplied to the bubble generation chamber through a supplying channel; a heat generating element drive device which drives the heat generating element to generate and expand an ejection bubble in the liquid in the bubble generation chamber so that the liquid in the bubble generation chamber is ejected from the nozzle by means of the ejection bubble; and an air bubble incorporation unit which incorporates air bubbles into the liquid stored in the liquid storage chamber.
