Fluid discharge head and image forming apparatus

Abstract

A fluid discharge head includes a fluid chamber filled with ink; a discharge opening configured to discharge a droplet of ink from the fluid chamber; a plurality of piezoelectric elements configured as displacement generating units to provide kinetic energy to the ink for the discharge of the ink droplet; and a vibrating plate forming a part of the fluid chamber and connected to the piezoelectric elements, the vibrating plate being configured to transmit a displacement generated by the piezoelectric elements to the ink in the fluid chamber. The vibrating plate includes vibrating portions for the respective the piezoelectric elements. The vibrating portions are configured to be independently displaced for the corresponding piezoelectric elements, and at least one of the piezoelectric elements is configured as a pressure detecting unit to detect an ink pressure in the fluid chamber.
