ABSTRACT:
In a jet recording method, a normally solid recording material is placed in a heat-melted state in a path defined by a nozzle leading to an ejection outlet and, in a recording step, is imparted with a thermal energy corresponding to a recording signal to generate a bubble, thus ejecting a droplet of the recording material out of the ejection outlet. As an improvement, prior to the recording step, the recording material is sucked or pressurized to be ejected out of the ejection outlet and, in the recording step, the bubble is communicated with ambience. As a result, the recording is started or resumed without discharge failure even after a long time of non-use or standing state.
