To provide a fixing solution and an image forming method in which faster fixing rate and faster drying rate can be achieved while the amount of fixing solution supplied is reduced and furthermore, a wet feeling in a formed image is reduced and an image having a high fixing strength can be formed.A fixing solution that softens a toner to fix a toner image constituted by the toner to an image support contains a hydroxyl group-containing ester compound expressed by general formula (1) below: R1—(CO)—O—R2  general formula (1): where R1 represents a linear or branched alkyl group having 6 to 11 carbon atoms, and R2 represents a linear or branched alkyl group having at least one hydroxyl group and 2 to 4 carbon atoms.
