Abstract:
1. A liquid ejecting head comprising: a plurality of nozzles, each including an ejection outlet for ejecting a droplet, an ejection energy generating element, disposed at a position opposing said ejection outlet, for generating energy for ejecting a droplet, a pressure chamber provided with said ejection energy generating element and fluidly communicating with said ejection outlet, and a supply passage for supplying the liquid to said pressure chamber, wherein said nozzles include a first nozzle and a second nozzle which are connected with respective supply passages having lengths different from each other, wherein said first nozzle and said second nozzle are disposed at one end portion with respect to a widthwise direction of an elongated supply chamber for supplying the liquid to said first nozzle, wherein a distance between said second nozzle and said supply chamber is greater than that between said first nozzle and said supply chamber, wherein said supply passage for said first nozzle extends in a direction perpendicular to a direction of liquid ejection from said ejection outlet and fluidly communicates with said supply chamber, and wherein said supply passage for said second nozzle extends in a direction parallel to the direction of liquid ejection.
