Abstract
In a highly integrated printing head forming an image with continuously ejected ink droplets, there are disadvantages of a high cost for a control circuit and wirings due to a large number of the wirings for charging electrodes, a difficulty for ensuring electrical insulation between the wirings having a narrow pitch and a high density, and an induced voltage in the wirings due to the mutual induction therebetween. Therefore, the present invention includes dividing a plurality of nozzles into a plurality of groups, shifting production timings between the groups, and applying a charging voltage via common wirings to which the charging electrodes of different groups corresponding to each other are commonly connected.
