Toner for forming electrophotographic image and developers using the same

A developer for developing an electrophotographic image comprising a toner and a carrier, wherein said toner comprises

• colored particles comprising a resin and a colorant,
• 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
• 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 .sigma. satisfying the condition of 10.ltoreq..sigma..ltoreq.30,
• said fine resin particles and said fine particles of an inorganic material (I) are fixed on the surface of said colored particles by mechanical impact, and said carrier is a negatively chargeable carrier comprising
• 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
• a fine particles of an inorganic material (II).
