Abstract: An ultraviolet curing ink can be sufficiently leveled, and attachment of, for example, dust can be prevented. In an ink-jet printer, a carriage capable of reciprocating in a scanning direction is mounted with an ink-jet head for ejecting a color ink and a clear ink and ultraviolet irradiation devices for emitting ultraviolet rays. A control unit performs control so that in the forward movement of the carriage, a color ink is ejected and applied to a medium, and in the backward movement of the carriage, ultraviolet rays are irradiated to the color ink deposited on the medium and the color ink is cured. Subsequently, the medium is fed in a feed direction, and the clear ink is ejected and applied to the surface of the cured color ink in the forward movement of the carriage. In the backward movement of the carriage, the clear ink applied to the medium is irradiated by ultraviolet rays and is cured.
