An ink composition includes a pigment; polymer particles; and a polar solvent with a boiling point of 150°C or higher, in which the polymer particles include a core polymer and a shell polymer that covers at least a portion of the core polymer, a glass transition point of the polymer that configures the core polymer is more than 30°C lower than the glass transition point of the polymer that configures the shell polymer, the polymer that configures the shell polymer includes a polymer having a (meth)acrylate monomer unit and a carboxylic acid monomer unit, the content (solid content conversion) of the polymer particles is 1.0 mass% to 10 mass% with respect to the total amount of the ink composition, and the content of the polar solvent is 10 mass% to 40 mass% of the total amount of the ink composition. |
