    摘要: In an ink jet head using a thermal energy for ejecting ink, this invention aims to reliably and uniformly remove kogations deposited on a heat application portion in contact with the ink. To realize this objective, the upper protective layer is arranged in an area including the heat application portion so that it can be electrically connected to serve as an electrode which causes an electrochemical reaction with the ink. The upper protective layer is formed of a material containing a metal which is dissolved by the electrochemical reaction and which does not form, on heating, an oxide film which hinders the dissolution. With this arrangement, a reliable electrochemical reaction can be produced to dissolve a surface layer of the upper protective layer, thereby removing kogations on the heat application portion reliably and uniformly.

    摘要: An inkjet recording apparatus includes a heating unit configured to produce thermal energy for discharging ink, and two electrodes which electrically connect with each other through the ink. Voltage is applied between the two electrodes, and a current value flowing through the ink is measured. Whether the ink is discharged or not is determined by determining whether the current changes when the heating unit is driven.

    摘要: An object of this invention is to drive different types of printing elements arranged in a printhead by proper powers without increasing the number of signal lines between the printhead and a printing apparatus main body, complicating the circuit configuration, and decreasing the printing speed. For this purpose, time division signals representing two driving periods corresponding to two types of printing elements are supplied to a printhead having the two types of printing elements which require different application powers in order to obtain a desired printing characteristic. Power is applied to the first type printing elements in the first driving period, and power is applied to the second type printing elements in the second driving period.
