Liquid-ejecting head, liquid-ejecting device, liquid-ejecting method, and ejection medium for liquid-ejecting head

Abstract

A liquid-ejecting head includes a liquid cell that contains an ejection medium that is liquid at normal temperature, a nozzle for ejecting the ejection medium in the liquid cell, an energy-generating element for supplying ejection energy to the ejection medium in the liquid cell, and heating means for heating the liquid cell independently of the supply of the ejection energy to the ejection medium in the liquid cell. The energy-generating element is driven to eject the ejection medium from the nozzle in a droplet form. The heating means is supplied with a substantially direct current component to generate heat so that at least the temperature of the liquid cell is constantly maintained above the ambient temperature irrespective of whether the energy-generating element is driven.
