Claim:
A liquid ejection apparatus, comprising: an ejection receiving medium conveyance device which has a conveyance face and conveys an ejection receiving medium placed on the conveyance face; a liquid ejection head of a full-line type which has nozzles ejecting liquid in a downward-facing state and pressure chambers connected to the nozzles, the nozzles ejecting the liquid toward the ejection receiving medium on the conveyance face, the nozzles being arranged on the liquid ejection head through a length corresponding to a width of the ejection receiving medium; a perpendicular movement device which moves the liquid ejection head in a direction perpendicular to the conveyance face; a turning device which turns the liquid ejection head to switch the nozzles of the liquid ejection head between the downward-facing state and an upward-facing state; and a sealing device which seals the nozzles when the nozzles of the liquid ejection head are in the upward-facing state, wherein the turning device performs a plurality of swinging operations consecutively to make the liquid ejection head swing to agitate the liquid inside the liquid ejection head, the liquid ejection head being inclined from side to side by a predetermined angle around the upward-facing state in each of the swinging operations.
