ABSTRACT:
In an electrostatic inkjet device having a plurality of ejection electrodes, when an ejection electrode is designated as an ejection dot, a potential of the ejection electrode is changed to an ejection level for a first time period. When the ejection electrode is not designated as an ejection dot, the potential of the ejection electrode is changed within a predetermined level different from a ground level such that ejection does not occur at the ejection electrode.
