An image forming method, including: a first process for ejecting liquid droplets of a radiation curable ink composition onto a recording medium from an ejection head capable of ejecting the radiation curable ink composition using an ink jet recording device; and a second process for irradiating the liquid droplets with active radiation by an irradiation measure capable of emitting the active radiation, in which, among the liquid droplets of the radiation curable ink composition irradiated with the active radiation, a difference of the total irradiation energy of a liquid droplet having the highest total irradiation energy of the active radiation and a liquid droplet having the lowest total irradiation energy of the active radiation in the second process is 30% or more and 50% or lower of the irradiation energy (E90) [mJ/cm2] required for curing 90% of the radiation curable ink composition. |
