The liquid ejection apparatus comprises: an ejection head having ejection holes which eject liquid droplets to land on an ejection receiving medium; a conveyance device which causes the ejection head and the ejection receiving medium to move relative to each other in one direction, by conveying at least one of the ejection head and the ejection receiving medium in a relative conveyance direction substantially perpendicular to a breadthways direction of the ejection receiving medium; a direction of flight deflecting device which deflects direction of flight of the liquid droplets ejected from the ejection head in a direction which includes at least a component that is substantially parallel to the relative conveyance direction; and a deflection control device which controls the direction of flight deflecting device, wherein when droplets are ejected during relative conveyance of the ejection receiving medium and a row of dots is formed in which dots that are mutually adjacent in the relative conveyance direction are at least partially overlapping with each other, the deflection control device changes landing positions of the liquid droplets by a droplet landing position change amount y which satisfies the following relationship: y=PtsxI, where Pts is a pitch between dots in the row of dots in the relative conveyance direction, I is an amount of shift comprising two or more types of integers of any value, and y is the droplet landing position change amount in the relative conveyance direction, thereby causing the droplets to land while avoiding consecutive landing of mutually adjacent dots.
