    摘要： To provide an image forming method capable of maintaining high friction fastness for a long period of time without impairing texture of a fabric.
    An image forming method of the present invention includes a step of applying an ink containing a pigment and resin particles onto a fabric by an inkjet method, and a step of applying a post-treatment liquid containing a lubricant onto the ink applied to the fabric in a wet-on-wet manner. When a solubility parameter of a resin constituting the resin particles is represented by SP 1 (cal/cm 3 ) 1/2 and a solubility parameter of the lubricant is represented by SP 2 (cal/cm 3 ) 1/2 , 0.3 ≤ SP 1 - SP 2 ≤ 0.8 is satisfied.
