Abstract
Provided is an ink jet recording method including: discharging first ultraviolet curable ink of a radical polymerization reaction type which contains a radical photopolymerization initiator and a radical polymerization compound and in which transmittance at a wavelength of 395 nm is equal to or less than 1%, onto a recording medium; and curing the first ultraviolet curable ink which is landed on the recording medium by irradiating the ink with ultraviolet light, in which a light source which initially emits the ultraviolet light in the curing of the ink is an ultraviolet light emitting diode in which peak intensity of the irradiated ultraviolet light is equal to or more than 800 mW/cm2.
