ABSTRACT:
This specification discloses a liquid discharging method of using a head having a first liquid flow path communicating with a discharge port, a second liquid flow path having an air bubble creating area, and a movable member having a free end on the discharge port side and disposed between the first liquid flow path and the air bubble creating area, to create an air bubble in the air bubble creating area, displace the free end of the movable member on the basis of pressure by the creation of the air bubble, and direct the pressure to the discharge port side of the first liquid flow path by the displacement of the movable member to thereby discharge liquid, wherein the internal pressure of the first liquid flow path and the internal pressure of the second liquid flow path are made to differ from each other. The specification also discloses a liquid discharging head for use in such liquid discharging method, a liquid discharging apparatus using such liquid discharging head, a recording system having such liquid discharging apparatus, a liquid container for use in the liquid discharging head, and a head cartridge having the liquid discharging head.
