摘要

A liquid discharging method for discharging liquid by displacing a movable member by means of a bubble created on the bubble generating area, which the free end of the movable member faces, comprises the step of promoting the movement of the free end of the movable member by means for promoting the displacement of the free end thereof. With the adoption of this method, the pressure of the bubble that acts upon the free end of the movable member enables the movable member to form an appropriate displacing configuration to lead the pressure exerted at the time of foaming and the development of the bubble in the discharging direction efficiently. At the same time, the displacement of the movable member is performed smoothly, thus contributing to enhancing the durability of the movable member. <IMAGE>
