The driving device is provided with a standard waveform generation section, a voltage amplification section, a plurality of current amplification sections and a selection section. Output terminals of the current amplification sections are commonly connected. The selection section selects at least one of the plurality of current amplification sections, in accordance with the number of the actuating elements to be driven concurrently or a printing density of an image to be printed by the recording head. The selection section inputs a driving signal, whose voltage component has been amplified by the voltage amplification section, to input terminal(s) of the selected current amplification section(s).
