Liquid discharging head and ink-jet apparatus

Abstract

A liquid discharging head and an ink-jet apparatus that can achieve stable discharging over time by suppressing clogging of a nozzle due to particles and the like contained in liquid, and by suppressing adhesion of particles to a channel and a diaphragm surface. A liquid discharging head includes a nozzle configured to discharge liquid; a pressure chamber communicated with the nozzle; an individual channel communicated with the pressure chamber through a narrow part; a common channel communicated with the individual channel; an energy generation element configured to generate energy; and a diaphragm configured to convey the energy to the pressure chamber, wherein a monomolecular film is formed at inner walls of the nozzle, the pressure chamber, the narrow part, the diaphragm, and the individual channel, the monomolecular film being lyophilic to the liquid.
