Description

ABSTRACT:
An ink jet head comprises a plurality of discharge openings for discharging ink, and a facing area of the head having the plurality of discharge openings arranged in lines, and then, on both sides of the plurality of discharge openings arranged in lines on the facing area, structures are arranged with a gap over such facing area. With the structures thus arranged, the mist, which is created by the rebounded ink droplets from the surface of a recording medium at the time of impact, is prevented from adhering to the circumference of the discharge openings on the facing area of the head, hence preventing ink discharges from being disabled or twisted.
