Abstract:
1. An image forming apparatus, comprising: an ink ejection head which deposits radiation-curable ink containing a coloring material onto a recording medium; a radiation curing device which irradiates the deposited radiation-curable ink on the recording medium with radiation to cure the deposited radiation-curable ink; an optical density change calculation device which stores optical density change values of the coloring material with respect to different irradiation conditions of the radiation, and calculates a variation in optical density change of the coloring material produced by difference in the irradiation conditions of the radiation; and a correction device which performs correction processing of a volume of the radiation-curable ink to be deposited on the recording medium according to the variation in the optical density change of the coloring material in the radiation-curable ink calculated by the optical density change calculation device.
