An aqueous ink composition having excellent temporal stability and good fixability of an image formed is provided. SOLUTION: A water-based ink composition, a colored particle containing a pigment and a dispersant having a hydrophobic structural unit represented by the following general formula (1), and a hydrophobic structure represented by the following general formula (2): Resin particles containing a self-dispersing polymer having units and an aqueous medium are contained. [Chemical 1] (In the formula, R 11 and R 21 represent a hydrogen atom or a methyl group. L 11 and L 21 represent —COO—, —OCO—, —CONR 3 — and the like. L 12 and L 22 represent 1 to C carbon atoms. At least 1 selected from the group consisting of 12 alkylene groups, alkenylene groups having 2 to 12 carbon atoms, —CO—, —NR 7 —, —O—, —S—, —SO—, and —SO 2 —. A divalent linking group comprising a seed, R 3 and R 7 each represent a hydrogen atom or an alkyl group, and Ar 1 and Ar 2 each represent a monovalent group having an aromatic ring) [Selection figure] None |
