A recording device includes: a head voltage control unit of setting target voltage of head voltage used to perform the recording operation by driving a recording head; a DC voltage generating unit generating drive voltage while giving a feedback so as to obtain a target voltage; and a smoothing capacitor connected between an output unit of the DC voltage generating unit and the recording head and having capacity which is twice or more as large as capacity of all of nozzles of the recording head driven at the same timing. The output voltage of the DC voltage generating unit is increased to the target voltage over predetermined time.
