Abstract
Disclosed is a liquid discharge method of discharging liquid with a liquid discharge head having a heating surface that contacts and heats the liquid and a discharge port that faces the heating surface and discharges the liquid. The method includes heating the liquid through the heating surface to generate a bubble such that the bubble communicates with an atmosphere, thereby discharging the liquid. The liquid that is being discharged from the discharge port includes a trailing portion. The trailing portion moves toward the heating surface in response to a reduction in volume of the bubble and contacts the heating surface. The method further includes heating the trailing portion through the heating surface while the trailing portion is in contact with the heating surface, thereby generating a bubble.
