A liquid discharge method for discharging a liquid through a discharge port for discharging the liquid utilizing a bubble by displacing a movable separation film for always substantially separating a first liquid flow path in communication with said discharge port for discharging the liquid from a second liquid flow path comprising a bubble-generating region for generating the bubble in said liquid, on the upstream side of said discharge port with respect to flow of the liquid in said first liquid flow path, comprises a step of displacing a downstream portion of said movable separation film toward said discharge port relatively more than an upstream portion of said movable separation film with respect to a direction of the flow of the liquid.
Cette invention concerne une méthode d'éjection de liquide par un orifice d'éjection, la méthode faisant appel à une bulle qui déplace une membrane de séparation servant à matérialiser un premier canal d'écoulement donnant sur l'orifice de refoulement et séparé d'un second canal d'écoulement comprenant une zone de formation de bulle en amont de l'orifice de refoulement et sous le premier canal d'écoulement, la bulle formée servant à déplacer une portion aval de la membrane de séparation vers l'orifice d'éjection plus qu'il ne déplace une portion amont de cette membrane vers l'axe du premier canal d'écoulement.
