Abstract
The present invention relates to an ink jet nozzle to eject ink. The nozzle comprises a body defining a chamber in which the ink to be ejected can be located and an aperture through which the ink is ejected in use. The nozzle further comprises an actuator member having shape memory which extends from the body into the chamber. The actuator member is arcuate in shape when in a quiescent state and straightens in shape when actuated. The actuator member is located in the chamber so as to push ink through the aperture when actuated to thereby eject ink from the body.
