NOZZLE PLATE FOR INK JET HEAD, HEAD, INK FOR INK JET RECORDING, INK JET RECORDING APPARATUS USING THEREOF, AND RECORDING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a highly reliable ink jet recording apparatus and method by improving a mechanical strength of an ink repellent layer in a nozzle plate having the ink repellent layer using silicone and ensuring functions as a nozzle surface such as discharge stability and cleaning performance.

SOLUTION: The nozzle plate for ink jet head comprises the ink repellent layer formed by curing silicone in the ink discharge surface side of a nozzle member, wherein the weight-average molecular weight Mw (Pr) of the uncured silicone and the weight-average molecular weight Mw (Ex) of toluene extraction of the cured silicone have the relation of the formula (1).
