Abstract
The ejection head comprises: an ejection aperture which ejects onto a receiving medium a liquid in which charged dispersion particles are dispersed in a solvent; a pressure chamber which contains the liquid; an ejection channel which connects the ejection aperture with the pressure chamber; a pressurizing device which applies an ejection pressure to the liquid; and an electrode pair provided facing a vicinity of a meniscus of the liquid inside the ejection channel for generating an electric field inside the ejection channel, wherein at least a portion of the charged dispersion particles are caused to move to a vicinity of at least one of the electrodes in the electrode pair by means of the electric field generated inside the ejection channel, and the liquid from which the at least the portion of the charged dispersion particles have been removed is ejected from the ejection aperture by the pressurizing device.
