PROBLEM TO BE SOLVED: To provide an inkjet recorder equipped with a nozzle array driving power source, which drives a plurality of nozzle arrays, has a simple circuit constitution, and is low-cost. SOLUTION: Nozzle array voltage converting parts 2-1 and 2-2 are equipped with: both dropper regulators 2-1-2-1 to 2-2-2-2 respectively corresponding to nozzle arrays 22-1 to 22-4; and switching regulators 2-1-1 and 2-2-1 which convert an output voltage of a main power source 8 that supplies an electric power for driving all of the nozzle arrays 22-1 to 22-4, and output the voltage to the dropper regulators 2-1-2-1 to 2-2-2-2. The dropper regulators 2-1-2-1 to 2-2-2-2 step down a voltage outputted from the switching regulator 2-1-1 or 2-2-1, and impress it to those corresponding to themselves among the nozzle arrays 22-1 to 22-4.
