NOZZLE PLATE FOR LIQUID EJECTOR HEAD, LIQUID EJECTOR HEAD, LIQUID EJECTOR, LIQUID EJECTION METHOD, INKJET RECORDING APPARATUS, AND INKJET RECORDING METHOD

摘要

The present invention provides a nozzle plate for liquid ejector head and a liquid ejector head. The nozzle plate for liquid ejector head includes at least a nozzle hole for ejecting droplets composed of an ejection liquid, wherein the surface energy of an inner wall of the nozzle hole at 25°C is lower than the surface tension of the ejection liquid at 25°C and is substantially same as the surface energy of the ejection side surface of the nozzle plate at 25°C.
