摘要： There is provided a liquid ejecting method using a liquid ejection head including a first ejection port for ejecting an ink containing a color material, a first energy generating element for generating energy utilized for ejecting the ink from the first ejection port, a second ejection port for ejecting an improvement liquid for improving recording property of the ink, and a second energy generating element for generating energy utilized for ejecting the improvement liquid from the second ejection port. The method includes ejecting the ink from the first ejection port by driving the first energy generating element, and ejecting the improvement liquid from the second ejection port by driving the second energy generating element, in a state where a liquid level of the improvement liquid in the second ejection port has moved forward in a liquid ejection direction than a liquid level of the ink in the first ejection port when the first energy generating element is driven.

摘要： A print head, which ejects ink by using a method whereby a bubble generated by a heat generating element communicates with the air, and for which the occurrence of cavitation is deterred and the durability is improved, is provided. According to the print head, a bubble grows until the maximum volume is attained, and then, at a volume reduction step, communicates with the air. As a result, a liquid in a bubble generation chamber is ejected. An ejection port and the heat generating element are arranged so that the center of the ejection port is shifted away from the center of the heat generating element in a direction leading from an ink supply port to the ejection port.

摘要： An ink jet recording head includes a nozzle array and discharge energy generation elements. The nozzles include discharge ports to discharge liquid when recording, pressure chambers to communicate with respective discharge ports, and liquid flow paths to supply liquid to the respective pressure chambers. The discharge energy generation elements apply discharge energy to the pressure chambers to discharge liquid from the nozzles in a predetermined order during time-division driving. Arranging intervals of the liquid flow paths take at least two different values. When a drive timing difference average between the adjacent discharge energy generation elements is calculated by a particular expression, a relationship of D≧Y is satisfied between an interval D and an interval Y in a k-th discharge energy generation element and a k+1-th discharge energy generation element positioned adjacent to the k-th discharge energy generation element. The intervals D and Y represent distances between particular liquid flow paths.

摘要： PROBLEM TO BE SOLVED: To provide a liquid discharge method which can realize recording having small impact positional deviations which is hard to be affected by an air flow since liquid droplets each having a small volume are discharged from a discharge port and are certainly united to become a large liquid droplet on the fly. SOLUTION: The shape of the discharge port is formed of two opening parts spaced apart, and a slit shape constricted connecting part for connecting the two opening parts. COPYRIGHT: (C)2009,JPO&INPIT

摘要：【課題】吐出口から外部に伸びた吐出液体が、吐出口内にある液体から分離するタイミングを大幅に早めることを可能とし、画質の低下を引き起こすサテライト及びミストの一層の低減を可能とする。
【解決手段】吐出口の中心に向かって突出する複数の突起部と、複数の突起部を繋ぐ複数の円弧部とを含む前記吐出口から、液体を前記吐出口から外方へ延在する柱状の液体としてせり出させ、複数の突起部の先端側の部分をつなぐように液体が伸張した状態で、かつ、円弧部によって形成される吐出口内の領域で液体が吐出する方向とは逆の方向に液体を移行させ、上記伸張した液体の液面が、円弧部によって形成される吐出口内の領域に形成される液面よりも吐出方向側に位置している状態で、上記柱状の液体と前記伸張した液体とを分離させて液滴を吐出する。
