Abstract
The present invention provides an image forming method capable of suppressing glossiness unevenness in one image with curability of an ink droplet having been caused to land on a recording medium increased. The image forming method includes: preparing an actinic radiation-curable inkjet ink containing a radical polymerizable compound, a photopolymerization initiator, a gelling agent, and a nucleating agent; discharging a droplet of the actinic radiation-curable inkjet ink to cause the droplet to land on a surface of a recording medium; and curing the droplet by irradiating the droplet having been caused to land on the recording medium with actinic radiation. The gelling agent contains, in a molecular structure thereof, a polar group, and a Calkyl group, the nucleating agent is a (poly)glycerin fatty acid ester, and an oxygen concentration in an atmosphere where irradiation with the actinic radiation is conducted is less than 20 vol %.
