摘要： An electrostatic ink jet recording head has a laminate structure for an electrode assembly disposed in an ink chamber of a head body. The laminate structure includes a first base film, a plurality of patterned recording electrodes, a plurality of patterned control electrodes and a second base film. The recording electrodes and control electrodes are alternately arranged one by one as viewed perpendicular to the laminate. The tips of the recording electrodes are located ahead of the tips of the control electrodes toward the opposite electrode. In operation, the control electrodes located on both sides of a specified recording electrode are applied with a high voltage pulse to eject liquid ink from the meniscus in the vicinity of the specified recording electrode. The ink jet recording head can be manufactured at low costs and with a higher density.

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： The invention relates to an apparatus for development of an electrostatic latent image formed on a carrier surface by a liquid developer. The apparatus has a developer carrier with a smooth surface to carry thereon the liquid developer, such as a rotating roller partially submerged int he liquid developer. When the image-carrying surface comes close to the surface of the developer carrier the electrostatic image attracts the developer liquid existing on the developer carrier surface. To ensure that the developer liquid rises and projects to reach the image-carrying surface exactly and exclusively in an area just opposite to the latent image, the smooth surface of the developer carrier is divided into a plurality of first regions which are provided by a first material and uniformly distributed over the entire area of the surface and a second region which is provided by a second material and occupies the spacings between the first regions, using a readily wettable material as the first material and a hardly wettable material as the second material, or an electrically conductive material as the first material and a dielectric material as the second material.

摘要： A developing unit includes a developer consumption calculator, a consumption shift unit, a supply amount setting unit and a developer supply controller. The developer consumption calculator calculates consumptions of developer in zones and stores the consumption in each zone into a corresponding storage region. The consumption shift unit shifts the consumption stored in the storage region corresponding to each zone to a storage region corresponding to a zone located on a downstream side in a developer conveyance direction in response to the conveying of the developer by the circulation conveyance member. The supply amount setting unit sets a supply amount from a developer supply portion based on the consumption stored in the storage region corresponding to the zone corresponding to the developer supply position. The developer supply controller controls supply of the developer from the developer supply portion based on the set supply amount.

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.
