Abstract: A liquid discharge method for discharging liquid by use of a liquid discharge head provided with liquid discharge nozzles having a plurality of electrothermal converting members capable of forming bubbles for discharging a liquid droplets comprises the step of using a driving condition in a range where the discharge speed of droplets is made substantially constant, while the amount of droplet is made changeable with the timing difference of driving when droplets are discharged by driving a plurality of the electrothermal converting members one after another. With the adoption of the method thus structured, high quality prints can be obtained without deviation of impact positions irrespective of the dot diameters, larger or smaller, for a significant enhancement of image representation.

Abstract: A liquid discharge head is provided which allows production of a recorded image of improved quality by controlling the speed of flow of a liquid and the distribution of the speed of flow in a flow path caused in consequence of contraction of bubbles thereby stabilizing the direction of satellites arising behind main drops of discharged liquid and, at the same time, decreasing the amount itself of the satellites. This liquid discharge head comprises a movable separation membrane capable of effecting separation between a first flow path (3) communicating with a discharge port (11) for discharging a liquid and a second flow path (4) furnished with a bubble generating region for generating bubbles in the liquid by means of a heating element (2) and a movable member (26) opposed to the bubble generating region across the movable separation membrane (5) and furnished in the direction of liquid discharge with a free end to guide the displacement of the movable separation membrane induced by the growth of the bubbles in the direction of the discharge port and regulate the shape of displacement of the movable separation membrane as well.
