Abstract
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.
