Abstract
An ink jet printer includes a carriage having a recording head for jetting ultraviolet curable ink and an ultraviolet irradiating device for curing an ink jetted on the recording medium with irradiation of ultraviolet rays such that an image is formed by scanning the carriage; and a maintenance unit for performing maintenance on the recording head at predetermined timing. It also includes a control section for controlling the maintenance unit so as to be converted to a masking state which becomes a head maintenance disabling state when an image is formed, and for controlling the maintenance unit so as to be converted to a non-masking state which becomes a head maintenance enabling state after securing a non-irradiating state in which the ultraviolet rays are not irradiated on the maintenance unit, by a function provided by a unit other than the maintenance unit when the head maintenance is performed.
