Zusammenfassung:1. Field of the Invention Liquid is discharged at a high frequency in a consecutive manner with a liquid discharge head having a movable member. A bubble formed for discharge a first discharged droplet grows large into a discharge port side by the movable substantially closing a common liquid chamber side in a bubble forming procedure, and disappears fast at the common liquid chamber side by the movable member releasing the common liquid chamber side of a flow path in a bubble disappearance procedure, and reaches a state to remain at the discharge port side of a heat-generating body. Under this state, since the bubble disappears at the common liquid chamber side, a constant liquid is refilled to reach the discharge port side, and the bubble does not yet completely disappear, a meniscus is disposed comparatively closer to a liquid discharge face. Under the circumstances, if discharge of a second discharged droplet is arranged to start from this state, the liquid can be discharged well at a short interval in a consecutive manner.
