Abstract

PURPOSE:To provide a titled recorded capable of preferably discharging ink liquid by elongating the meniscus of the ink by electrostatic force and flying the ink droplet by the variation in the abrupt pressure gradient produced by the curve of an air stream. CONSTITUTION:40m/s<=va<=150m/s, da<=250mum, di<=100mum, 10mum<=Ta<= 2.5da are set, where da represents the diameter of an air exhaust port 1, va represents an air flow rate, di represents the diameter of an ink exhaust port 4, and Ta represents the interval between the air exhaust port and the ink exhaust port. A signal source 5 is electrically connected to a conductive ink supply tube 6 which communicates with a nozzle plate 2 and the ink exhaust port 4 so that a potential difference is produced between the plate 2 and the port 4.
