Abstract
The liquid ejection apparatus has: a liquid ejection head having a liquid ejection surface in which a plurality of liquid ejection ports which eject liquid are arranged; a pressure adjustment device which adjusts pressure in the liquid ejection head; a head drive device which applies selectively, to the liquid ejection head, a liquid ejection drive waveform which causes the liquid to be ejected from the liquid ejection ports of the liquid ejection head, wherein: a first sliding motion is performed in a state where interior of the liquid ejection head is pressurized by the pressure adjusting device to set the surface of the liquid of each of the liquid ejection ports to a projecting shape, and where a meniscus slight vibration waveform is applied to the liquid ejection head by the head drive device, in such a manner that the liquid ejection surface is wetted by the liquid.
