Abstract
A printer includes an inductor connected in a power supply line to piezoelectric elements for ejecting ink. When a drive voltage rises or falls, an undershoot and an overshoot which become large in proportion to the number of the driven piezoelectric elements are caused in a drive current by the inductor. As a result, when the number of the driven piezoelectric elements increases, the drive voltage for driving the piezoelectric elements increases and the pressure applied to the ink increases. Thus, the decrease in the ink ejection speed due to the influence of a crosstalk phenomenon can be avoided, and hence an image formed on a paper becomes more even.
