摘要： A continuous liquid ejection head collects droplets which are not used for printing (unused droplets) without affecting the flight of droplets which are used for printing (used droplets). An ejection nozzle and a collection nozzle collect an unused droplet by causing a liquid surface to project out from the aperture of the collection nozzle so as to be positioned in the trajectory along which droplets ejected from the ejection nozzle fly, causing the unused droplet to collide and unite with the liquid surface projected from the collection nozzle, and causing the liquid surface to retreat.

摘要： A liquid ejection head which does not stop a printing action even if mist of ink adheres onto the orifice plate, particularly between ejection port arrays, and suppresses deposition of continuously-adhered mist of ink. On the printing head part, there is formed a recovery hole which communicates with the common liquid chamber and recovers the ink adhered onto the orifice plate in the printing head part into the common liquid chamber. A face is provided with function of an ink guide in the printing head part so as the ink adhered to the printing head part to be guided to the recovery hole.
