An ink jet recording method uses an ink jet recording apparatus including a plurality of heads (52A-D) arranged in parallel in a first direction, each of which ejects droplets of a different radiation-curable ink composition onto a recording medium (P), and first light sources (90A-H) provided for corresponding heads so as to be disposed at a predetermined side of the corresponding heads. The first light sources emit active radiation to irradiate the droplets on the recording medium. The method includes ejecting droplets of the ink compositions from the heads onto the recording medium, and performing a first irradiation by irradiating the droplets of each ink composition with the active radiation from the corresponding first light source at an irradiation energy within 500 ms after the droplets have landed. The irradiation energy is in the range of 5% to 10% of the energy E 90 at which the ink composition is 90% cured. |
