Liquid ejecting head and liquid ejecting apparatus
Abstract:
A charge accumulated on an insulative nozzle plate flows into the ink with which nozzle openings and pressure generation chambers are filled and reaches a vibration plate. The charge that has reached the vibration plate is driven out therethrough because the vibration plate is made of a conductive ceramic material and is grounded. Therefore, it is possible to obtain an ink jet recording head in which insulation breakdown of the vibration plate caused by the charge accumulated on the vibration plate is suppressed from occurring and a driving circuit is suppressed from being damaged.
