Amine A, which is an amine compound having an α-hydrogen atom and having a number average molecular weight of less than 1000, amine B, which is an amine compound having an α-hydrogen atom and having a number average molecular weight of 1000 or more, a monofunctional radical polymerizable monomer, and a bifunctional radical. It contains at least one of the polymerizable monomers, and the total content of the monofunctional radical polymerizable monomer and the bifunctional radical polymerizable monomer is 50% by mass or more based on the total amount of the photocurable ink composition. Photocurable ink composition and image forming method. |
