Abstract: 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.

Abstract: Provided are an image forming apparatus and an image forming method capable of coping with a medium exceeding a transport limit of a pair of rollers in image formation in which the medium is transported with the medium interposed between the pair of rollers. In a case where a medium exceeding a transport limit of first transport means to which medium transport using a first roller and a second roller is applied is used, second transport means is used to assist in the medium transport performed by the first transport means. The driving of second driving means for driving the second transport means is controlled using a driving signal applied to the driving control of the first driving means for driving the first transport means. Medium transport in which synchronization is taken between the first transport means and the second transport means is realized.

Abstract: According to an aspect of the present invention, by switching off the provisional curing device on the rear side in the direction of travel of the scanning direction, droplet ejection is carried out without performing provisional curing of the ink immediately after droplet ejection. The provisional curing of the ink is carried out by the provisional curing device on the front side in the direction of travel of the scanning direction, during scanning in the opposite direction to that during droplet ejection.
