A liquid ejection apparatus including: a flushing-operation-data producing section which produces flushing-operation data for flashing of ink; a second-liquid-ejection-data producing section which produces data about ejection of treatment liquid such that (i) the treatment liquid is to be landed on a dot area on which the ink is to be landed upon forming an image dot among dot areas and (ii) an amount of the treatment liquid landed to be on at least one dot area on which the ink is to be landed upon flashing of the ink is made smaller, by referring the flushing-operation data produced by the flushing-operation-data producing section, than an amount of the treatment liquid to be landed on a dot area on which the ink is not to be landed upon flashing; and a second-liquid controlling section which controls a head on the basis of the data produced by the second-liquid-ejection-data producing section.
