Disclosed herein is a liquid discharging method, comprising using a liquid-discharge head equipped with a discharge opening from which a liquid is discharged, a first region to which a first liquid is supplied, a bubble-generating region containing a second liquid and generating bubbles in the second liquid, and a movable member which is displaceable between a first position opposite to the bubble-generating region and a second position within the first region and apart from the bubble-generating region and has a support part more upstream than its free end, in which the movable member is displaced from the first position toward the second position with the generation of a bubble in the bubble-generating region, and the bubble is guided to the discharge opening by the movable member, wherein the first liquid and the second liquid have no compatibility with each other.

La présente porte sur une méthode de distribution de liquide. Cette méthode comprend l'utilisation d'une tête distributrice de liquide comportant une ouverture pour l'écoulement du liquide, une première zone où le premier liquide est acheminé, une zone contenant un second liquide dans laquelle sont produites des bulles, ainsi qu'un élément mobile pouvant se déplacer d'une première position opposée à la zone où sont produites les bulles à une seconde position à l'intérieur de la première zone et éloignée de la zone où sont produites les bulles. La tête distributrice comprend une partie de support plus en amont que son extrémité libre, dans laquelle l'élément mobile est déplacé de la première position à la seconde position lors de la production d'une bulle dans la zone servant à cette fin. La bulle est acheminée vers l'ouverture d'écoulement par l'élément mobile. Le premier liquide et le second liquide ne sont pas compatibles.
