<P>PROBLEM TO BE SOLVED: To provide a technique of reducing crosstalk, which is generated when employing a shared-wall inkjet head, by simple drive control with lower power consumption than in the past. <P>SOLUTION: When ink is ejected from any one of a plurality of pressure chambers, an electric field pulse, which corresponds to an electric field pulse to be applied to a partition wall forming a pressure chamber which is to eject the ink, and has at least one square wave, which is in a direction opposite to that of the electric field pulse and has a pulse width corresponding to the electric field pulse, is applied to a partition wall adjacent to the partition wall forming the pressure chamber which is to eject the ink. <P>COPYRIGHT: (C)2011,JPO&INPIT |
