Curing processing is realized according to differences in absorption characteristics of activation light among inks and characteristics of layers to be formed with the inks. A scanning device reciprocally moves in a first direction an inkjet head including a first nozzle array ejecting a first ink and a second nozzle array ejecting a second ink; a relative movement device relatively moves a recording medium in a second direction with respect to the head; an ejection control device divides the nozzle array into regions in the second direction and controls ink ejection for each unit of the divided nozzle region; an activation light irradiation device irradiates the inks deposited on the medium with the activation light; an irradiation region dividing device divides an irradiation range into divided irradiation regions corresponding respectively to the divided nozzle regions; and a light quantity control device controls light quantities respectively for the divided irradiation regions.
