Abstract
A liquid ejection method is provided which ejects small-volume droplets from ejection openings and causes them to reliably combine together on the fly into a large droplet that is less susceptible to influences of air flows, thus realizing a printing with reduced droplet landing position deviations. To that end, each of the ejection openings is constructed of two openings spaced apart and a slit-like constricted connection portion that connects the two openings together.
