Patent Number: 6,305,783

Title: Liquid discharge method, liquid discharge head, manufacturing method of the head, head cartridge, and liquid discharge device

Abstract: A liquid discharge method is disclosed which comprises a displacement step where a movable member is displaced by generating an electrostatic force between a substrate having a thermal energy generating element for generating thermal energy which is utilized to discharge a liquid through a discharge port and the movable member disposed opposite to the thermal energy generating element and having a free end on a downstream side in the flow direction of the liquid to thereby displace a liquid surface at the discharge port to an upstream side in the flow direction of the liquid; and a discharge step where the movable member is displaced owing to a bubble formed by the thermal energy generated by the thermal energy generating element to discharge the liquid through the discharge port. In addition, there are also herein disclosed a liquid discharge head, a manufacturing method of the head, a head cartridge, a liquid discharge device, and the like.
