ABSTRACT:
A liquid droplet ejecting recording head includes a wall defining a chamber for being filled with recording liquid, said wall having a portion for defining an orifice communicated with the chamber; and a thin-film resistor provided on a surface of the wall facing the chamber so as to be located in the chamber, the thin-film resistor having one surface facing the chamber with which the thin-film resistor may be exposed to the recording liquid contained in the chamber, the thin-film resistor being energized with pulsed electric current for generating pulsed heat to directly heat the recording liquid, to thereby allow the recording liquid to be ejected outside through the orifice from the chamber in the form of a droplet and to be attached onto a surface of image recording medium positioned in confrontation with the orifice.
