Abstract: The image forming method includes: applying two or more kinds of ink compositions having different hues onto a recording medium to form a multi-color image, each ink composition containing a pigment, water, and 5% by mass to 15% by mass of polyvalent (meth)acrylamide represented by the following formula (1) with respect to the total amount of the ink composition; and applying a treatment solution, containing an aggregation component onto the recording medium. In the image forming method, an average diameter φ1 (μm) of droplets of the ink compositions on the recording medium satisfies the following relational expression (1), and an application density of droplets having a minimum volume of ink composition on the recording medium is 80% or more (Q: n-valent linking group, R1: H, methyl group, n≧2). (2.54×10000/R)×1.5≦φ1≦(2.54×10000/R)×1.7  Relational Expression (1) wherein, R represents a resolution (dot per inch) of an image.
