摘要： In the liquid ejecting apparatus, a potential controller that is capable of switching states between a same potential state where potentials at a predetermined portion at the side of the liquid ejecting unit and a predetermined portion at the side of the ejected medium supporting unit are the same and a potential difference generation state where a potential difference is generated between the predetermined portion at the side of the liquid ejecting unit and the predetermined portion at the side of the ejected medium supporting unit. The potential controller forms the same potential state while the ejected medium is transported by the ejected medium transportation unit, and the potential controller forms the potential difference generation state in at least appropriate period while the ejected medium is not transported by the ejected medium transportation unit.

摘要： A conductive nozzle plate is formed with a nozzle orifice. An insulative layer is formed on a first face of the nozzle plate. A head body includes a pressure chamber adapted to contain liquid therein and a pressure generating element operable to cause pressure fluctuation in the liquid. The head body is attached to a second face of the nozzle plate so as to communicate the pressure chamber with the nozzle orifice. The second face of the nozzle plate and the head body are fixed to a head case. A conductive head cover covers a part of the first face of the nozzle plate while exposing the nozzle orifice. A part of the nozzle plate and the head cover directly come into contact with each other.

摘要： An object is to provide a fine forging method for forming partitions of recesses precisely and forming recess shapes for pressure generation chambers etc. with high accuracy as well as a liquid ejection head that is produced by using the fine forming method. A fine forging method for forming groove-shaped recesses that are arranged at a prescribed pitch. After groove-shaped recesses are formed tentatively in a material plate by a first punch in which tentative forming punches are arranged, finish forming is performed on the tentatively formed groove-shaped recesses by using a second punch in which finish forming punches are arranged. An end portion of a projection strip is formed with slant faces or a slant face, whereby an end portion of each groove-shaped recess is formed precisely. A liquid ejection head produced by the above method exhibits stable liquid ejection characteristics and its manufacturing cost can be reduced by virtue of simplified working of forging.
