Abstract
An ejection inspection method includes: preparing a liquid ejection nozzle for ejecting liquid onto a recording medium; irradiating a pattern formed by the liquid ejected onto the recording medium with light; and conducting ejection inspection of the liquid ejection nozzle based on results of observing or recognizing reflected light or transmitted light of the light from the recording medium. The recording medium includes an ink absorption layer having light transmittance where a great number of void cells having a particle diameter smaller than wavelength of the light are dispersed into a joining material, and an ejection amount of the liquid is adjusted such that a region where the liquid is sufficiently filled in the void cells and a region where substantially no liquid is filled exist in a thickness direction and a horizontal direction in planar view of the ink absorption layer.
