摘要： A liquid discharge head at least comprises a discharge opening for discharging the liquid, a liquid flow channel in communication with the discharge opening and for supplying the liquid to the discharge opening, a substrate equipped with a heat generator for producing a bubble in the liquid that is filled in the liquid flow channel, and a movable plate supported and fixed onto the substrate at a position of the substrate opposed to the heat generator and with a gap from the substrate, with a free end on the discharge opening side. The liquid discharge head can discharge the liquid from the discharge openings by forcing the free end of the movable plate to be displaced toward the discharge opening around a fulcrum portion made near a support and fixing portion of the movable plate with the substrate due to pressure caused by produced bubble.

摘要： A liquid discharge method is designed for a liquid jet head provided with first discharge openings, a first liquid flow path conductively connected with each of the first discharge openings, first energy generating devices for generating energy for the discharge of droplets from the first discharge openings, second discharge openings, a second liquid flow path conductively connected with each of the second discharge openings, and second energy generating devices for generating energy for the discharge of droplets from the second discharge openings. Then, preceding the discharge of the first droplet from the discharge opening at a first discharge speed v.sub.1, the second droplet is discharged from the second discharge opening at a second discharge speed v.sub.2 smaller than the first discharge speed, and before each of the liquid droplets being impacted on an object, the first liquid droplet and the second liquid droplet are allowed to collide with each other to be combined. In this way, it becomes possible to allow two droplets to be in contact or to collide with each other reliably to be mixed between the liquid jet head and the object within a range that does not render any hinderance practically even if discharge speeds may fluctuate, hence obtaining precise images in higher quality.
