A liquid droplet ejection apparatus includes a conveyor unit that conveys
a recording medium, liquid droplet ejection head that records an image by
ejecting liquid droplets onto the recording medium conveyed by the
conveyor unit, and a controller that increases or decreases ejection
timing of the liquid droplet ejection head in amounts equal to a
correction time determined based on conveyance speed data of the conveyor
unit such that a shift amount generated in a period from when the liquid
droplet is ejected to when the liquid droplet lands on the recording
medium becomes constant with respect to a reference position.
