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 system for monitoring the toner content in ink. The system comprising a light source and a photo-detector disposed in a ink chamber wall, a controller and a display unit. A content-monitoring voltage V1 and an operation-checking voltage V2 are determined from experiments in advance. V1 and V2 are such light source voltages when a predetermined current Ith is obtained from the photo-detector for the minimum and maximum allowable toner contents, respectively. In usual operation in user site, operation of the system is checked with the light source voltage set for V2 in response to a power-on or a reset. Then, a monitoring of the toner content is started with the light source voltage set for V1. In a toner content monitoring, the sensor current is checked to see if it is equal to or larger than Ith.

摘要： An electrostatic ink jet record head of the present invention includes an ink chamber storing ink consisting of a carrier liquid and charged toner particles dispersed therein. An ejection port communicates the ink chamber to the outside of the head. An ejection electrode is disposed in the ejection port and electrically insulated from the ink. An electrophoresis electrode is positioned at the opposite side to the ejection electrode with respect to the ink chamber and electrically insulated from the ink. A control electrode is provided between the electrophoresis electrode and the ejection electrode and contacts the ink. Also, an electrostatic ink jet recorder of the present invention has, in addition to the head, a counter electrode facing the ejection port with the intermediary of a recording medium, and voltage controller for applying a particular preselected voltage to each of the discharge electrode, electrophoresis electrode, and control electrode. The voltage applied to the electrophoresis electrode is higher than a threshold voltage causing the toner particles to fly by themselves, while the voltage applied to the control electrode is lower than the threshold voltage.

摘要： In an ink jet type head assembly, a plurality of auxiliary electrodes alternate with a plurality of ejection electrodes. A voltage of the same polarity as charge deposited on toner particles is applied to two of the auxiliary electrodes adjoining an ejection electrode which should eject ink. This successfully prevents the toner particles from migrating toward the auxiliary electrodes away from the ejection electrode.

摘要： A recording head includes an ink chamber storing ink containing electrified toner particles and having an ejection opening 7 at one end and an ejection electrodes for ejecting the toner particles from the ejection opening. A counter electrode 6 faces the ejection opening. The recording head also includes a toner, concentration detection sensor detects a potential of the ejection opening 7, and a control unit for deciding a detected toner concentration and controlling a voltage to be applied to the ejection electrodes. The surface potential nearby ejection opening or the toner concentration and a voltage applying time are made to previously correspond to each other and are stored in a ROM table. A stable printing quality is obtained by detecting the toner concentration near the ejection opening by the toner concentration detection circuit and controlling a voltage to be applied to the ejection electrodes corresponding to a detected value.

摘要： An electrostatic ink jet according to the present invention includes a head body having an ink chamber for holding ink liquid containing charged particulate material; an ejection port provided at one end of that head body and connecting to the ink chamber; an ejection electrode arranged near this ejection port and fed with an ejection voltage of the same polarity as the charge characteristic of the charged particulate material; a counter electrode arranged opposite to the ejection port via a recording medium; and a pair of stirring electrodes. The stirring electrodes are arranged in the direction reverse to that of gravity in the ink chamber. The stirring electrodes are fed with a stirring voltage for shifting the charge particulate material in the direction reverse to the direction of gravity, and that stirring voltage is generated before the generation of the ejection voltage. As a result, the toner particulates are prevented from precipitating before the ejection of ink, and their concentration in the ink liquid in the ink chamber is generally uniformized.
