摘要： An ink jet apparatus electrifies ink in a nozzle, and ejects the ink from an ink ejecting hole onto a printing medium by a first electric field generated between the nozzle and the printing medium. The apparatus includes an ink catching device including an ink catching portion adjacent to the nozzle that catches an ejected substance. Between the nozzle and the ink catching portion, the apparatus applies a voltage for generating a second electric field which (i) causes an ejected substance, formed from the ink or the ink whose viscosity is changed, to be ejected from the nozzle, and (ii) causes the ink catching portion to attract the ejected substance. The apparatus, utilizes an electrostatic force to eject fluid, removes a clogging of an ejection head at any position, realizes less initial ejection fluctuation and improves the reliability of ejection.

摘要： An inkjet head (1) has a liquid flow path section (3) for receiving liquid and, in response to application of a voltage, ejecting the liquid to an object on which a drawing is to be made. The degree of design freedom of the shape of the liquid channel section (3) or the shape of a liquid channel in the liquid channel section (3) can be improved because the liquid channel section (3) is formed on the upper surface of a substrate. Furthermore, the inkjet head can have a structure corresponding to the properties of liquid to be ejected or to an object to which the liquid is to be ejected.

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.

摘要： An ink ejector includes a head movement control section (22), an ink ejection area recognition section (3), an ink ejection timing control section (23), and an ink droplet number calculating section (5). With this arrangement, it is possible to cause nozzles included in a nozzle array to eject ink at different timings and gradually increase an amount of ink to be ejected. This allows a film thickness of an ink ejection area after landing of ink droplets to be uniform. As a result, it is possible to form a good-quality film. Further, since a head (7) includes a nozzle array having a plurality of nozzles (10), it is possible to shorten the amount of time required to restore a defective pixel. Thus, it is possible to provide an ink ejector and an ink ejection control method in which a good-quality film having a uniform thickness can be formed, and the amount of time required to restore a defective pixel can be shortened.
