Abstract
The liquid droplet ejection head comprises: first nozzles which eject droplets of a first liquid to an ejection receiving medium; second nozzles which eject droplets of a second liquid to the ejection receiving medium; first pressure chambers which are connected to the first nozzles and filled with the first liquid to be ejected from the first nozzles; first pressure generating devices which cause the first liquid to be ejected from the first nozzles by applying pressure to the first liquid inside the first pressure chambers; second pressure chambers which are connected to the second nozzles and filled with the second liquid to be ejected from the second nozzles; and second pressure generating devices which cause the second liquid to be ejected from the second nozzles by applying pressure to the second liquid inside the second pressure chambers, wherein the first nozzles and the second nozzles are arranged in a two-dimensional array and disposed adjacently in mutual proximity so as to be aligned in a sub-scanning direction which is parallel to a relative direction of movement of the ejection receiving medium and the liquid droplet ejection head, in such a manner that the first liqu…
