An inkjet printing apparatus comprising: a head configured to eject light-curing ink which hardens if being subjected to irradiation with light, onto a recording medium; irradiators (11A, 11B) configured to irradiate the ink ejected from the head, with light; and an irradiation controller configured to control light irradiation of the irradiators (11A, 11B), wherein the head is configured to relatively reciprocate with respect to a mounting table for mounting the recording medium, the irradiators (11A, 11B) are disposed such that they are lined up in the relative reciprocation direction and the head is disposed between two irradiators (11A, 11B), and the irradiators (11A, 11B) are configured to relatively reciprocate in the same direction as the relative reciprocation direction with respect to the mounting table, together with the head, and characterized in that the irradiation controller is configured to perform control such that an outward-way illumination intensity, which is the illumination intensity of light to be radiated from the irradiators (11A, 11B) onto ink ejected from a certain nozzle of the head on the outward way of the reciprocating movement, and a homeward-way illumination intensity, which is the illumination intensity of light to be radiated from the irradiators (11A, 11B) onto ink ejected from the certain nozzle on the homeward way of the reciprocating movement, are set such that the one of the outward-way and the homeward-way illumination intensity for which a time from when the ink lands on the recording medium to when the ink is irradiated with light is longer is higher than the other illumination intensity for which a time from when the ink lands on the recording medium to when the ink is irradiated with light is shorter, and both of the outward-way illumination intensity and the homeward-way illumination intensity are set such that the diameters of dots (d1... d3) formed by the ink that has landed on the recording medium fall within a predetermined range. a head configured to eject light-curing ink which hardens if being subjected to irradiation with light, onto a recording medium; irradiators (11A, 11B) configured to irradiate the ink ejected from the head, with light; and an irradiation controller configured to control light irradiation of the irradiators (11A, 11B), wherein the head is configured to relatively reciprocate with respect to a mounting table for mounting the recording medium, the irradiators (11A, 11B) are disposed such that they are lined up in the relative reciprocation direction and the head is disposed between two irradiators (11A, 11B), and the irradiators (11A, 11B) are configured to relatively reciprocate in the same direction as the relative reciprocation direction with respect to the mounting table, together with the head, and characterized in that the irradiation controller is configured to perform control such that an outward-way illumination intensity, which is the illumination intensity of light to be radiated from the irradiators (11A, 11B) onto ink ejected from a certain nozzle of the head on the outward way of the reciprocating movement, and a homeward-way illumination intensity, which is the illumination intensity of light to be radiated from the irradiators (11A, 11B) onto ink ejected from the certain nozzle on the homeward way of the reciprocating movement, are set such that the one of the outward-way and the homeward-way illumination intensity for which a time from when the ink lands on the recording medium to when the ink is irradiated with light is longer is higher than the other illumination intensity for which a time from when the ink lands on the recording medium to when the ink is irradiated with light is shorter, and both of the outward-way illumination intensity and the homeward-way illumination intensity are set such that the diameters of dots (d1... d3) formed by the ink that has landed on the recording medium fall within a predetermined range.
