Abstract
A recording apparatus has a nozzle (10a) containing a viscous substance (11) of a viscosity not lower than 300 cP. A recording electrode (12) is disposed on the nozzle (10a) at a position near the forward end of the nozzle (10a). A meniscus (13) of the viscous substance (11) is formed on the forward end of the nozzle (10a), and then an electric pulse signal corresponding to an image signal is applied to the recording electrode (12) to vibrate the meniscus (13) or to separate a small droplet of the viscous substance (11) from the meniscus (13) and to make the droplet fly. The droplet adheres to a recording medium (15) disposed opposite to the nozzle (10a) for recording. The timing of a droplet discharging operation for thus discharging droplets of the viscous substance (11) and the discharge amount of the viscous substance (11) can be controlled through the control of the pulse width or the amplitude of the voltage pulses of the electric pulse signal.
