ABSTRACT:
A liquid ejecting recording process using a liquid ejecting recording head comprises a liquid discharging portion including an orifice for ejecting liquid droplets and a heat acting portion communicated with said orifice, said heat acting portion being a portion where heat energy for discharging liquid droplets acts to a liquid, and an electrothermal transducer having a structure laminated on a substrate with the layers mentioned below in the following order a lower layer, a resistive heater layer, and an upper layer from the substrate to the heat acting portion on the position of the heat acting portion, characterized in that when a signal voltage is applied to said resistive heater layer and potentials generating at two electrodes A and B connected with said resistive heater layer are represented by V.sub.A and V.sub.B, respectively, potential V applied to at least the surface portion of said upper layer is kept intermediate between V.sub.A and V.sub.B at least while said signal voltage is applied to said resistive heater layer.
