摘要： With a micro nozzle in which the fluid discharge head has a nozzle with a micro hole having a diameter of 0.01 μm to 25 μm, the drive voltage during discharging operation is reduced. Further, by disposing an electrode section for applying a drive voltage to a discharge fluid on an external wall of a nozzle section, a distance between the electrode section and the nozzle hole is shortened. With this structure, the subject invention achieves both miniaturization of nozzle and reduction in drive voltage in an electrostatic suction type fluid discharge device. The subject invention also achieves an increase in discharge limit frequency while allowing use of materials with higher resistance for the fluid to be discharged.

摘要： An ink jet apparatus electrifies ink (2) in a nozzle (4), and ejects the ink (2) from an ink ejecting hole (4b) onto a printing medium (8) by a first electric field generated between the nozzle (4) and the printing medium (8). The ink jet apparatus includes an ink catching device which includes an ink catching portion (14) provided at a position adjacent to the nozzle (4) and catches an ejected substance ejected from the nozzle (4). In addition, between the nozzle (4) and the ink catching portion (14), the ink jet apparatus applies a voltage for generating a second electric field which (i) causes the ejected substance, which is formed from the ink (2) or the ink (2) whose viscosity is changed, to be ejected from the nozzle (4) and (ii) causes the ink catching portion to attract the ejected substance. With this, in a configuration which utilizes an electrostatic force to eject fluid, it is possible to promptly remove a clogging of an ejection head at any position, and it is also possible to realize less initial ejection fluctuation and improve the reliability of ejection.
