Abstract
Disclosed is a thermal electrostatic ink-jet recording apparatus comprising a head body provided with an ink chamber, electrodes for selectively applying heat, in response to image signals to each of discrete ink unit areas corresponding to pel density, and electrodes for producing a predetermined electrostatic field between an ink surface and a recording sheet so as to jet the heated ink unit areas by applying the electrostatic field, in which electric current is passed through an organic resistance film to heat the ink.
Claims12
A thermal electrostatic ink-jet recording apparatus comprising:
- (a) a recording head body having an orifice side and a back side;
- (b) first and second spaced apart wall members in said body defining an ink chamber for accommodating ink therein, said first wall member being on said orifice side and said second wall member being on said back side of said head body, and one of said wall members comprising an electrically conductive organic resistance film;
- (c) orifice means in one of said wall members in flow communication with said chamber for jetting ink therefrom;
- (d) thermal energy applying means for applying thermal energy to selected portions of said ink adjacent said orifice means in response to image signals, including a plurality of spaced apart electrical current conducting electrodes in contact with said film to pass an electric current through said film and thereby heat selected areas of said ink in response to image signals;
- and
- (e) electrostatic field applying means for applying an electrostatic field between said ink and a recording sheet to jet said ink from said orifice means.
