Abstract:
A liquid discharging method which employs a liquid discharging head comprising a liquid discharging port communicating with a liquid flow path; a bubble generating region in said flow path where a bubble is generated in liquid in said flow path; and a movable member extending along said flow path and having a free end which is moveable and a fulcrum which is fixed, wherein said free end can move between a first position and a second position which is located at a point farther from the bubble generating region compared with the first position in response to an expansion of a bubble generated in said bubble generating region; wherein said movable member is movable from the first position to said second position by a pressure of said bubble generated in said bubble generating region in order to discharge the liquid out of said liquid discharging port, said method comprising the steps of:providing said movable member with said free end in a downstream direction with respect to said fulcrum and applying discharging energy to said liquid in said bubble generating region in an amount which causes saturation wherein an amount of liquid discharged does not change substantially with increases in said discharging energy.
