摘要:
A liquid discharging method for a liquid head discharge head, which is provided with a plurality of discharge ports for discharging liquid, a plurality of liquid flow paths communicated always with each of the discharge ports at one end, each having bubble generating area for creating bubble in liquid, bubble generating means for generating energy to create and grow the bubble, a plurality of liquid supply ports each arranged for each of the liquid flow paths to be communicated with common liquid supply chamber, and movable member supported with minute gap to the liquid supply port on the liquid flow path side, and provided with free end, the area of the movable member surrounded at least by the free end portion and both sides continued therefrom being made larger than the opening area of the liquid supply port facing the liquid flow path, comprises the step of setting a period for the movable member to close and essentially cut off the opening area during the period from the application of driving voltage to the bubble generating means to the substantial termination of isotropical growth of the entire bubble by the bubble generating means, hence making it possible to enhance the suppressing efficiency of the bubble growing component in the direction opposite to the discharge port, and the refilling characteristics of liquid simultaneously.
