Abstract
A liquid ejection method includes preparing a head comprising an ejection outlet for ejecting the liquid, a bubble generation region for generating the bubble in the liquid, a movable member disposed faced to the bubble generation region and displaceable between a first position and a second position further from the bubble generation region than the first position; displacing the movable member from the first position to the second position by pressure produced by the generation of the bubble in the bubble generating portion to permit expansion of the bubble more in a downstream side closer to the ejection outlet than in an upstream side; supplying, to a heat generating element for applying thermal energy to the bubble generating region, a driving pulse divided into a first pulse and an adjacent second pulse with interval time therebetween; pre-heating the liquid by the first pulse to an extent not enough to eject the liquid through the ejection outlet; generating a bubble by heating the liquid by the second pulse to eject the liquid through the ejection outlet;
controlling a degree of pre-heating of the liquid by changing at least one of a pulse width of the first pulse or the interval time.
controlling a degree of pre-heating of the liquid by changing at least one of a pulse width of the first pulse or the interval time.
