Ink-jet recording apparatus
 An ink-jet recording apparatus applies a pressure, which is higher than atmospheric pressure, to an ink supply. A recording head includes a nozzle for jetting ink droplets. A valve is disposed between the pressurized ink supply and the nozzle in order to control the ink flow to the nozzle. The valve is opened in response to a recording signal only when ink droplets are to be jetted from said nozzle.
