Abstract
An ejection device includes a nozzle that ejects an ejection fluid, an ejection-side pump, a driving-side pump, and a heating unit. The ejection-side pump includes a pressure transmitting member, and an ejection chamber and a driving chamber adjacent to each other across the pressure transmitting member. The ejection chamber is filled with the ejection fluid. The driving chamber is filled with a driving fluid. The driving-side pump is a pump that applies pressure to the driving fluid. The pressure transmitting member transmits the pressure applied to the driving fluid to the ejection fluid in the ejection chamber. The heating unit heats at least the ejection-side pump while the driving-side pump remains unheated.
