Droplet discharging head and image forming apparatus
Abstract:
A droplet discharging head includes: a nozzle substrate that includes a nozzle opening to discharge a droplet therethrough; a liquid chamber substrate that includes liquid pressure chambers communicating with the nozzle openings; a vibration plate arranged to face the nozzle substrate with the liquid chamber substrate interposed therebetween; piezoelectric elements that are provided to face the liquid pressure chambers with the vibration plate interposed therebetween and are arranged in a predetermined direction; a driving element provided, in a flip-chip implementation, on a flow path substrate that includes the nozzle substrate, the liquid chamber substrate, the vibration plate, and the piezoelectric elements; and a first reinforcing wire that is disposed to at least one of the flow path substrate and the driving element, has a band shape extending in a direction along a row of the piezoelectric elements, and is connected to a common electrode shared by the piezoelectric elements.
