Claim:
1. A liquid ejection head comprising: an ejection port array that ejects droplets to a printing medium while moving relative to the printing medium; and at least one gas blowing port disposed with reference to the ejection port array that blows gas as the ejection port array ejects droplets to the printing medium, wherein the gas blowing port blows gas, where the gas is blown at a speed equal to or lower than a maximum speed at which no vortex due to the gas is generated when only the gas is blown from the gas blowing port, to an upstream side of an airflow of a vortex generated in an area between an ejection port surface of the ejection port array and the printing medium while the liquid ejection head is moving relative to the printing medium, the gas blowing port being disposed at a position within a distance between the ejection port surface and the printing medium from the ejection port array.
