Inkjet recording apparatus and image forming method

An inkjet recording apparatus (10) has: an image forming means (23) including a nozzle row (61) having a plurality of nozzles for ejecting ink being to be curable by irradiation of an active light beam; a scanning means (28, 30) which causes the image forming means (23) to move in a scanning direction; a relative movement means (42, 44) which causes relative movement between the recording medium (12) and the image forming means (23); a first active light beam irradiation means (32A, 32B) which radiates an active light beam onto the ink so as to provisionally cure the ink; a second active light beam irradiation means (34A, 34B) which radiates an active light beam having an irradiation light quantity for fully curing the ink; an ejection control means (112) which controls ink ejection from the nozzle row (61), for each of the plurality of nozzle groups (61Y-1, 61M-1, 61C-1, 61K-1, 61LC-1, 61LM-1, 61Y-2, 61 M-2, 61C-2, 61K-2, 61 LC-2, 61 LM-2, 61CL-1, 61 CL-2, 61CL-3); and an irradiation control means (108) which controls irradiation of the active light beam of the first active light beam irradiation means (32A, 32B), with respect to each of a plurality of irradiation units (32A-1, 32A-2, 32B-1, 32B-2), according to an irradiation light quantity which is set with respect to each of the plurality of irradiation units (32A-1, 32A-2, 32B-1, 32B-2).
