    摘要: There is disclosed a liquid discharge head comprising: a plurality of discharge ports for discharging a liquid; a plurality of liquid flow paths whose one end portion always communicates with each of the discharge ports and which comprise a bubble generating area for generating a bubble in the liquid; bubble generating means for generating an energy to generate and grow the bubble; a plurality of liquid supply ports, disposed in the liquid flow paths, for communicating with a common liquid supply chamber; and a movable member having a free end supported at a slight gap with respect to the liquid flow path of the liquid supply port, so that recording of a high quality level image is achieved at a high speed. When a volume of a liquid droplet discharged from the discharge port is Vd, and during discharge of the liquid from the discharge port, a drawing volume from the discharge port to a liquid surface retracted to maximum into the liquid flow path is Vm, a relation of Vd>Vm is established. Therefore, meniscus returns fast, and a refill frequency can be enhanced.
