Inkjet recording apparatus and control method for the same

摘要

An inkjet recording apparatus includes a plurality of ejection electrodes (101) and a counter electrode (108) which are controlled at predetermined intervals (TP) such that a first voltage pulse is applied to a selected ejection electrode depending on input data and a second voltage pulse is applied to the counter electrode in synchronization with the first voltage pulse. The first and second voltage pulses produce a voltage difference (VP + VOS) between the selected ejection electrode and the second electrode, wherein the voltage difference is not smaller than a predetermined threshold voltage (VTH) which is a minimum value which causes ejection of particulate matter from the selected ejection electrode.
