摘要:
For stabilizing the liquid discharge from the head such as in the ink jet recording the invention provides a liquid discharging head comprising a discharge liquid path communicating with a discharge opening for discharging a discharge liquid and adapted to flow the discharge liquid, a bubble generating liquid path including a bubble generating area for bubble generation and adapted to flow a bubble generating liquid and a movable separating membrane adapted for mutually and substantially separating the discharge liquid path and the bubble generating liquid path and having a recess, in a position corresponding to the bubble generating area, deviated so as to narrow the bubble generating liquid path, wherein the recess has substantially non-displacing corner portions and is adapted to displace, excluding the corner portions, by a bubble generated in the bubble generating area.
