ABSTRACT:
An ink jet nozzle head comprising a first nozzle head member having a surface on which hydrophilic sections of a predetermined width and hydrophobic sections of a predetermined width are formed alternately and in parallel with one another, and a second nozzle head member having a surface of the same configuration as the surface of the first nozzle head member, these members being opposed to each other to form a very small space therebetween, whereby a plurality of nozzles are formed along the hydrophilic sections. The hydrophilic sections of the second nozzle head member may be positioned just above those of the first member or offset therefrom. The nozzle openings formed between the two members are formed to have acute angle edges.
