Abstract
An ejection apparatus for ejecting material from a liquid at a plurality of ejection locations () disposed in a row, has a plurality of channels () through each of which liquid flows in use to or from a respective ejection location at an open end of the channel. An ejection electrode () is disposed at each ejection location by means of which an electric field is created in use to cause the ejection of material from the liquid. An electrically conductive path () exists to each ejection electrode for supplying a voltage to the ejection electrode () in use. The channels () are isolated from one another and the electrically conductive paths () are separated from the channels over substantially the whole of their length.
