    摘要： The present invention provides a toner for developing an electrostatic latent image which suppresses an adhesion and wearability on a surface of a photosensitive member and exhibits an excellent rising property of an electrification. The toner comprises (i) toner particles containing a binder resin and a colorant, (ii) a first external additive consisting of first inorganic particles whose number-average particle size is 5-40 nm, (iii) a second external additive consisting of second inorganic particles whose number-average particle size, which is larger than that of the first external additive, is 20-160 nm, (iv) a third external additive consisting of third inorganic particles whose number-average particle size, which is larger than that of the second external additive, is 80-1200 nm, and (v) a fourth external additive consisting of a metal salt of fatty acid whose volume-average particle size is 1.5-12 &mgr;m, said four external additives being externally added to the toner particles.
