PURPOSE:To make a uniform recording possible by a method wherein a heating resistor is arranged in the ink-pressure room provided corresponding to each of the multioriffice and the ink temperature at each ink pressure room is adjusted definitely. CONSTITUTION:In the multioriffice ink jet head having a manifold where a plurality of ink pressure rooms 3 are provided for ink jetting, the upper plate 1 of the ink jet head is made from piezoelectric ceramic material to give oscillation to the pressure room 3 and the lower plate 2 is made from alumina material. And on the bottoms of cavity parts constructing the ink pressure rooms 3 of alumina material are printed heating resistor coats 10 and connector coats 12 are printed in order to connect the terminals of each resistor coat 10 with each other. Hereby, the quantity of applied electrical current to each resistor coat 10 is adjusted so that the ink temperature can be controlled. |
