<p>The present invention can perform a favorable curing process in accordance with the differences in absorption characteristics of active rays of respective inks, and characteristics of layers to be formed by the respective inks. The present invention is provided with: a scanning means for reciprocating an inkjet head (24) in the first direction, the inkjet head (24) comprising a first nozzle array (61Y, M, C, K, LC, LM) for discharging a first ink and a second nozzle array (61W) for discharging a second ink; a relative movement means for moving a recording medium relative to the inkjet head (24) in the second direction; a discharge control means for dividing the nozzle array (61) into a plurality of regions in the second direction, and controlling the discharge of ink for each unit (61-1, 61-2) of the divided nozzle regions; an active ray irradiation means (32A, 32B) for irradiating active rays to the ink attached on the recording medium; an irradiation region dividing means for dividing the irradiation range into a plurality of regions (32A-1, 32A-2, 32B-1, 32B-2) corresponding to the respective divided nozzle regions; and a light intensity control means for controlling the light intensity of the divided irradiation regions with respect to each region.</p> |
