| 主权项 | 1. An image forming method, comprising: a liquid composition applying step of applying a liquid composition to a recording medium; an ink applying step of applying an ink to the recording medium in such a manner as to be at least partially overlapped with a region to which the liquid composition is applied; and a heating step of heating the recording medium to which the liquid composition and the ink are applied, wherein the ink contains a self-dispersible pigment and resin particles, the liquid composition contains: an agglomerating component of agglomerating at least either the self-dispersible pigment or the resin particles; andwax particles, a heating temperature TH in the heating step, a softening point Tmp of the resin particles, and a melting point Tmw of the wax particles satisfy a relationship of Tmp<Tmw≦TH, a penetration specified by JIS K2235 of the wax particle is 5 or less, and an application amount to the recording medium of wax particles X having a particle diameter equal to or larger than a film thickness D represented by Expression (1) shown below among the wax particles is 0.01 g/m2 or more; D=a×(b1/c1+b2/c2), Expression (1): wherein, in the expression, a is an application amount (g/m2) to the recording medium of the ink, b1 is a content (% by mass) of the self-dispersible pigment in the ink, c1 is a specific gravity of the self-dispersible pigment, b2 is a content (% by mass) of the resin particles in the ink, and c2 is a specific gravity of the resin particles. | ||
