Liquid ejection method and liquid ejection apparatus

The present invention provides a liquid ejection method and a liquid ejection apparatus which enables small droplets each of diameter at most 10 μm to be stably ejected and which allows a sufficient number of droplets to be ejected per unit time. A heater is allowed to generate heat to eject a main droplet and a liquid column from an ejection port; the liquid column is to be separated into a plurality of sub-droplets. A relationship (L/L)≧0.9 is set for the length L of the liquid column observed immediately after the liquid column has been separated from the main droplet and from a liquid in the ejection port and the length L of the liquid column observed immediately before the liquid column is separated into the plurality of droplets.
