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.

摘要： A liquid discharge head comprises a separation member for separating the discharge liquid flow paths communicated with discharge ports for discharging discharge liquid to enable discharge liquid to flow, and the bubbling liquid flow paths to enable bubbling liquid to flow, which is provided with the bubble generating areas for creating bubbles used for discharging discharge liquid from the discharge ports. This separation member is provided with the opening portions positioned to face the bubble generating areas, and displacement members provided for the separation member corresponding to the openings, having the free ends to be displaced by bubbles created on the bubble generating areas provided for the separation member. Then, with no bubbles created on the bubble generating areas, the displacement members interrupt the opening portions, and with bubbles created thereon, the free ends of the displacement members are displaced to discharge discharge liquid from the discharge ports of the head. Hence, this head can prevent discharge liquid from entering around the heat generating members at the time of bubble disappearance, and the mixture of discharge liquid and bubbling liquid when the head is left intact for a long time, while maintaining the excellent discharge efficiency by means of the displacement members thus arranged.
