The liquid ejection apparatus comprises: a liquid ejection head including an ejection port surface on which a plurality of ejection ports for ejecting a liquid toward a recording medium are arranged; a drive condition selection device which selects at least one of drive conditions for the liquid ejection head in order to eject the liquid from the ejection ports, the drive conditions including a first drive condition in which individual performance variations among the liquid droplet ejection heads in relation to ejection performance are reflected, and a second drive condition in which ambient environmental changes are reflected on the first drive condition; and an ejection failure determination device which performs determination of ejection state of the liquid, wherein, if the liquid ejection head is driven under the second drive condition during normal ejection, then the liquid ejection head is driven during the determination of the ejection state under a drive condition in which an ejection performance is equal to or less than that of the first drive condition.
