An object of the present invention is to provide a toner which has stable cleaning properties and can be fixed at a low temperature and can prevent filming contamination on a photoreceptor and a developing roller. A toner composition containing, as a toner binder, a modified polyester resin capable of reacting with a compound having an active hydrogen group in an organic solvent is dissolved or dispersed, and the dissolved or dispersed product is dissolved in an aqueous medium containing fine resin particles. In the toner for developing an electrostatic image obtained by dispersing and reacting with a crosslinking agent and / or an elongating agent and removing the solvent from the obtained dispersion, the glass transition point (Tg) of the resin fine particles is 40 to 40. At 100 ° C., the weight average molecular weight is from 9000 to 200,000, and the content of the resin fine particles with respect to the toner particles is from 0.5 to 5.0 wt%.
