An ink jet recording apparatus, having a control circuit for controlling the driving of a recording head and a driver circuit for driving the recording head, includes an AC/DC converting circuit for converting an input AC voltage into a first DC voltage to then supply the first DC voltage to the driver circuit, and a voltage converting circuit for converting the first DC voltage into a second DC voltage to then supply the second DC voltage to the control circuit, and when the AC voltage is interrupted, for keeping the second DC voltage higher than a reset voltage of the control circuit until the first DC voltage drops to at least a guarantee voltage of the recording head.
