Abstract:
1. An image forming method comprising: imparting ink to form an image by an ink composition being imparted on a recording medium using an ink jet method; drying the image which is formed on the recording medium; and curing the image by the image after the drying being irradiated with an active energy ray, wherein the recording medium has one or a plurality of pigment layers on at least one surface of a support with cellulose pulp as a main component, a transference amount of pure water into the recording medium which is measured by a dynamic scanning absorptometer is equal to or more than 1 ml/m the ink composition includes a pigment, water, and a water soluble polymerizable compound where the content ratio of the polymerizable compound with regard to total mass of the composition is equal to or more than 15 mass % and less than 40 mass %, and the content of a water soluble organic solvent with regard to the total mass of the composition is less than 3 mass %, the polymerizable compound includes a monofunctional acrylamide represented by a general formula (1) where n=1 and a multi-functional acrylamide represented by the general formula (1) where n is two or more, and the content of the monofunctional acrylamide with regard to total mass of the composition is equal to or more than 10 mass %, wherein in the general formula (1), Q represents a n-valent group and R
