Abstract
A liquid droplet ejection apparatus includes: a flow path unit including first and second pressure chambers for first and second liquids, respectively, and first and second nozzles communicating with the first and second pressure chambers, respectively, each of the first and second nozzles including a tip opening; and a pressure generating unit which generates a pressure for the liquids in the first and second pressure chambers to eject the liquids through the tip openings of the first and second nozzles. A diameter of the tip opening of the first nozzle is larger than that of the tip opening of the second nozzle and a length of the first nozzle is shorter than that of the second nozzle.
