ABSTRACT:
A driving circuit for an ink jet recording head that includes electrothermal converting elements for causing liquid emission by thermal energy. Electric energy is supplied to the electrothermal converting elements for actuation. Resistor elements are respectively and electrically connected parallel to the electrothermal converting elements for the purpose of reducing the influence of the capacitative component of the electrothermal converting elements to a negligible level, thereby suppressing electric current through the ink.
