Abstract
There is provided an ultraviolet ray irradiating apparatus configured to cure an ultraviolet-curable ink, the ultraviolet ray irradiating apparatus including a plurality of light emitting chips configured to emit an ultraviolet ray and arranged with a first pitch in main scanning direction and with a second pitch greater than the first pitch in sub scanning direction. The printing object includes a low part in which a distance from an ultraviolet ray irradiation surface becomes to be a large gap and a high part in which the distance from the ultraviolet ray irradiation surface becomes to be a small gap. The ultraviolet ray irradiating apparatus is configured to irradiate the object such that an illuminance, of the ultraviolet ray is not less than a minimum illuminance required for curing, in an area, of the low part, onto which the ink is discharged by a nozzle outermost in the sub scanning direction.
