An aqueous ink composition including: an aqueous medium and resin fine particles, in which a proportion of a high-boiling solvent occupied in the aqueous medium is 3% by mass or less, and a resin constituting the resin fine particle contains constitutional units represented by General Formula (1) or (2).
In the formulae, R1 represents a hydrogen atom or an alkyl group having 1 to 4 carbon atoms, A1 represents -O-, -NH-, or -N(L2-Y2)-, and L1 and L2 each are represent a specific divalent group such as an alkylene group or the like.
Y1 and Y2 each represent -OH, -OR2, -NH2, -NR2H, -NR2R3, -SH, -S(=O)2OM, or -OP(=O)(OM)2. R2 and R3 each represent a specific substituent, and M represents a hydrogen atom, an alkali metal ion, or an ammonium ion.
