An ink composition includes: water-insoluble polymer particles having a colorant and a water-insoluble polymer; and a compound represented by the following Formula (A), wherein the content of free polymer derived from the water-insoluble polymer is 1.0% by mass or less with respect to the total mass of the ink composition: wherein, R1 and R2 each independently represent a hydrogen atom or a hydrocarbon group having 1 to 22 carbon atoms; R3 represents a divalent hydrocarbon group having 1 to 18 carbon atoms; R1 and R2 may be the same as or different from each other, but R1 and R2 do not both represent a hydrogen atom at the same time; R1 to R3 may each have a substituent; m and n each independently represent an average addition mole number of AO of from 0 to 30; and AO represents an alkylene oxy group.
