ABSTRACT:
A method for preparing a liquid jet recording head which is to be used for generating heat energy to be utilized for discharging ink by applying electrical signals, having an electricity-heat energy convertor comprising a heat-generating resistor and a pair of electrodes for applying electrical signals on said heat-generating resistor, comprises the process of aging by heat treating the heat-generating resistor by applying electrical signals to said electrodes sufficient to stabilize the resistance value of said heat-generating resistor.
