METHOD OF MANUFACTURING INK JET RECORDING SYSTEM AND RECORDING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a method of manufacturing an ink jet recording system having improved ink filling performance and high reliability, in the method of manufacturing the ink jet recording system including an ink jet recording head in which part of a pressurization chamber wall face comprises a piezoelectric element.SOLUTION: A method of manufacturing an ink jet recording system including an ink jet recording head in which part of a wall face of a pressurization chamber 2 having a nozzle 3 installed therein is formed of a piezoelectric element 8 and in which a pressure wave is applied to ink in the pressurization chamber by operating and deforming the piezoelectric element to discharge ink droplets from the nozzle includes an evaluation process of evaluating ink filling performance when the piezoelectric element satisfies a formula (1) in the case that an average inclination &Dgr;a of a piezoelectric element surface is 0.1-1.0 rad, ink includes a surface active agent and a surface active agent concentration C is in a range of 0.01-1.0 time of a critical micelle concentration CMC in a vehicle.
