Claim Text:
1. An ink jet recording method, comprising: scanning a recording medium with an ink jet head and simultaneously discharging an ultraviolet-curable ink composition from the ink jet head to adhere the ink composition to the recording medium; irradiating the ultraviolet-curable ink composition adhered to the recording medium with at least a first ultraviolet irradiation and a second or subsequent ultraviolet irradiation; and wiping a nozzle of the ink jet head, from which the ultraviolet-curable ink composition has been discharged, using a nozzle wiping member, wherein the ultraviolet-curable ink composition contains a color material, a polymerizable compound having a di- or higher functional (meth)acryloyl group, a photopolymerization initiator, and a hindered amine compound, wherein the energy of the first ultraviolet irradiation is less than the energy of the second or subsequent ultraviolet irradiation, wherein the first ultraviolet irradiation is performed downstream of the recording medium transporting direction past the ink jet head and the second ultraviolet irradiation is performed on the downstream side of the recording medium transporting direction past the position at which the first ultraviolet irradiation is performed, and wherein an irradiation intensity of a light source in the second Of subsequent ultraviolet irradiation is 5 mW/cm
