摘要： 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.

摘要： A head body is shaped to project toward an ink ejection side, and formed along the projection with an ink channel for circulating the ink, at the vertex of the front end of which an opening is formed for ejecting the ink from the ink channel. An ejection electrode is formed along the front end of the head body. Its front end reaches the opening. An electrophoresis electrode is secured in the ink channel at a position opposite to the opening, and supplied with a voltage for moving the toner particles in the ink flowing in the ink channel to the front end of the ejection electrode with the electrophoresis effect. An opposite electrode is positioned opposite to the ink ejection side. A drive circuit drives the opposite electrode when the electrophoresis electrode is driven, and generates voltage for attracting the toner particles toward the opposite electrode with Coulomb force that is generated by an electric field acting between the ejection electrode and the electrophoresis electrode, and the opposite electrode.

摘要： An inkjet recording apparatus includes K ejection electrodes and K gate electrodes corresponding to the K ejection electrodes, respectively, which are located at a distance from the K ejection electrodes. The K gate electrodes are divided into M blocks each having N gate electrodes electrically connected in common. A first voltage pulse is applied to a selected one of N groups each formed by electrically connecting an i.sup.th (1.ltoreq.i.ltoreq.N) ejection electrode for each block to each other and a second voltage pulse is applied to a selected one of the M blocks. A voltage difference is generated between a group and a block which are selected from the N groups and the M blocks depending on an input signal, wherein the voltage difference is equal to or greater than a minimum voltage difference which causes ejection of an ejection electrode.

摘要： An electrostatic ink jet printing head includes a head block made of insulating material having a first surface and a second surface which are intercrossing substantially at a right angle. A plurality of ink channel grooves are formed on the first surface and the second surface in directions perpendicular to a ridge between the two surfaces. A plurality of recording electrodes are formed on convexities between the ink channel grooves and near ejection points located on the ridge. A cover is attached to the head block for covering the ink channel grooves and exposing the ejection points to the air. Ink is forcibly circulated by a forcible ink circulation means such as a pump. The recording electrodes are formed in the lower reaches of the ink stream compared to the ejection points, and a plurality of electrophoresis electrodes are formed in the ink channel grooves in the upper reaches of the ink stream compared to the ejection points. According to the electrostatic ink jet printing head, excessively higher concentration of the toner particles at the ejection points is prevented and stable ejection of the ink from each ejection point can be executed independently of history of ejection of each recording electrode, and stable ejection of the ink from definite and precise ejection points can be executed, thereby high precision clear printing is realized with a simple structure of the head and at a low cost.
