    摘要： An ink jet recording head has a plurality of discharge energy generating devices for discharging recording liquid, while being provided with a recording element base plate arranged on the face opposite to the surface where the devices are arranged, having a plurality of recording liquid supply ports for supplying recording liquid to the devices, as well as with a supporting member that holds and fixes the recording element base plate. For the supporting member, a plurality of recording liquid supply paths are arranged to supply recording liquid to each of the supply ports of the recording element base plate, respectively, and then, the flow path width of each supply flow path is formed to be smaller than the opening width of inlet portion of each supply port. Further, the steps to be created between the supply flow path and the supply port is buried by the bonding agent forced out from the bonding face of the recording element base plate and the supporting member. With the structure thus arranged, the ink jet recording head is capable of optimizing the discharge characteristics of recording liquid and the supply characteristics thereof, as well as the positioning precision of a recording element base plate to a supporting member.

    摘要： A process for producing an ink jet head having ink discharging outlets, a substrate with energy generating elements that discharge ink, ink pathways aligned with the energy generating elements and communicated with the ink discharging outlets, and a liquid chamber for storing and supplying ink into the ink pathways. The process involves providing first and second substrates, forming on the first substrate a first solid layer having a pattern for forming ink pathways while using a surface of the first substrate as bottom walls for the ink pathways, forming on the first solid layer a second solid layer with a pattern for the liquid chamber, laminating the second substrate on the first substrate such that the opening of the second substrate is sealed by the second solid layer, to obtain a stacked body with space for forming circumferential walls for the ink pathways and liquid chamber, filling the space with hardening material, hardening the hardening material, and dissolving the first and second solid layers of the stacked body to remove the first and second solid layers, thereby forming the liquid chamber and ink supplying pathways.

    摘要： An ink jet recording apparatus of the present invention has an ink jet recording head having an orifice from which an ink drop is ejected and an energy generation means for ejecting an ink fluid in the orifice. A first electrode is formed in the orifice and is connected electrically to the ink fluid. A second electrode is formed in an opposite position to the orifice with a designated distance from the orifice. A voltage controller applies a first voltage during a time period from a time when an ink fluid is ejected from the orifice to a time when the ink fluid is separated in 2 or more ink drops during traveling, and immediately after applying the first voltage, applies a second voltage which has an identical polarity to a polarity of the first voltage and has an absolute value less than an absolute value of the first voltage.
