ABSTRACT:
A toner for forming an electrophotographic image is disclosed. The toner comprises (1) colored particles comprising a resin and a colorant, (2) fine resin particles comprising a polymer formed by condensation of melamine and formaldehyde, and have a volume average diameter of 0.01 .mu.m to 1.0 .mu.m, and (3) fine particles of an inorganic material (I) having a volume average diameter of 0.01 .mu.m to 0.20 .mu.m and a standard deviation of distribution of the volume average diameter G satisfying the condition of 10.ltoreq..sigma..ltoreq.30. It is particularly preferred that the toner is used as a tow componet developer together with a negatively chargeable carrier which comprises (1) magnetic core particles each coated with a coating layer comprising a mixture of homopolymer of an alicyclic methacrylate monomer and a homopolymer of an acyclic methacrylate monomer, or a copolymer of an alicyclic methacrylate monomer and an acyclic methacrylate monomer, and (2) a fine particles of an inorganic material (II).
