Abstract

A liquid ejection apparatus, including: a conveyor; and an ejector to eject a liquid; wherein each of an upstream roller pair, a first downstream roller pair, and a second downstream roller pair of the conveyor includes upper and lower rollers to respectively contact front and back surfaces of a recording medium, at least one of the upper and lower rollers being configured to give a conveyance force to the recording medium, wherein a rotation speed of the second downstream roller pair is higher than that of the first downstream roller pair, and the conveyance force of the first downstream roller pair is larger than that of the second downstream roller pair, and wherein the conveyance force of the second downstream roller pair is largest at a position thereof in the first direction which is nearest to the central position of the second downstream roller pair.
