A toner is provided for developing an electrostatic image which has relatively high roundness, uniform shape, excellent property of electrification, electrification stability, maintenance of heat resistance, fixability, image quality and productivity, and is effective for full-color image formation, cleanerless system and toner-recycling system. The toner comprises toner particles containing a binder resin (A), a polymer (B) and a colorant, the polymer (B) having weight-average molecular weight of 1000-3000 and a ratio of weight-average molecular weight/number-average molecular weight of not more than 2.0, wherein the polymer (B) particles exist on surfaces of the toner particles.
