Claim:
1. An inkjet printing apparatus configured to perform a printing operation on a recording medium set on a platen in a plurality of passes, the inkjet printing apparatus comprising: a head that reciprocates in a main scanning direction while discharging an ink curable by being irradiated with light on the recording medium; an irradiator having a plurality of irradiation elements divided correspondingly to respective ones of the passes and configured to irradiate the ink on the recording medium with light; and an irradiation controller programmed to control the plurality of irradiation elements, wherein the plurality of irradiation elements are controlled by the irradiation controller so as to turn on ones of the plurality of irradiation elements corresponding to the passes before and inclusive of a (n−m)th pass, and so as to turn off or control ones of the plurality of irradiation elements corresponding to a last (m)th pass to have a lower illuminance than the ones of the plurality of irradiation elements corresponding to the passes before and inclusive of the (n−m)th pass, where the number of the plurality of passes is n (m is an integer smaller than n and greater than or equal to 1), so that the ink discharged in the last (m)th pass on the recording medium remains uncured.
