摘要： An electrostatic ink-jet recording device which provides stable printing by preventing too much charged toner from gathering around an ink discharge aperture even if the charged toner has not been discharged for a long time. If the charged toner is not to be discharged, the potential difference between the electrophoretic electrode and the discharge electrode is so controlled as to suppress electrophoretic movement of the charged toner toward the ink discharging aperture, or the potential difference is made zero. If the charged toner is to be discharged, the voltage applied to the discharge electrode is kept lower than the voltage applied to the electrophoretic electrode for a predetermined period of time before discharging a jet of the charged toner.

摘要： An ink jet recording head includes ejection electrodes arranged along ink paths that each have an ink outlet at one end and communicate with an ink chamber at the other end. The ejection electrodes are arranged in electrode sets, each set consisting of a number of ejection electrodes. The electrode sets have their corresponding ejection electrodes short-circuited, and are provided with control electrodes that are each common to respective ejection electrodes of a corresponding electrode set, and that are rearwardly offset from front ends of the ejection electrodes in an ink discharge direction. A voltage driver selectively imposes a voltage to groups of electrodes to provide a discharge biasing function, and selectively imposes a lower potential than a potential of the ejection electrodes to the control electrodes to provide a discharge restricting function.

摘要： An electrostatic ink jet recording head of a drop-on-demand type has a head body defining an ink chamber for receiving liquid ink containing charged toner particles, a set of electrodes for migrating the liquid ink by electrophoresis and ejecting the liquid ink from an ejecting slit of the ink chamber, and an ink reservoir, disposed above the ink chamber, for circulating the liquid ink by gravity between the ink reservoir and the ink chamber. A flow resistance against the liquid ink in the flow path from the outlet port of the ink chamber to the ink reservoir is smaller than a meniscus force generated by meniscuses formed at the ejecting slit to effectively eject the liquid ink without a pump and without an ink leakage.

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 electrostatic ink jet recording apparatus has a head body having an ink chamber in which ink charged to a specified polarity is stored, a plurality of ink ejection ports and a plurality of ejection electrodes. An ejection electrode drive circuit generates an ejection voltage to drive the plurality of ejection electrodes according to a time division method so that the ejection voltage is not simultaneously supplied to the adjacent ejection electrodes. A plurality of opposite electrodes are opposed to the plurality of ejection electrodes via recording paper. They are separated into first opposite electrodes corresponding to those ejection electrodes which are selectively being driven according to the time division method and second opposite electrodes corresponding to those ejection electrodes which are not being driven according to the time division method. An opposite potential setting circuit sets a first potential for the first opposite electrodes and a second potential for the second opposite electrodes. The first potential is set at such a value as to cause ink ejected from the ink ejection ports to be electrically attracted to the first opposite electrodes more strongly than to the second opposite electrodes.

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.
