An ink composition with excellent solvent resistance of the recorded image and fixability to a recording medium which may be applicable to an ink jet recording method, and an image forming method using the ink composition are provided. An ink composition which includes a dispersion medium including (a) water, and particles of (b) a polymer compound and (b) the polymer compound includes a repeating unit having a partial structure represented by the following General Formula (1) is provided. In the following General Formula (1), Ra and Rb, each independently, represent an alkyl group having the number of carbon atoms 1 to 4, and Ra and Rb may be bonded to each other to form an alicyclic structure with 4- to 6-membered ring and * represents a bonding site to a main chain or a side chain in the polymer compound. |
