Electrophotographic developer

An electrophotographic developer comprising:

• a toner containing a coloring agent and a binder resin, said binder resin having an acid value of 3 to 40;
• and
• a carrier, said carrier including a core material with a cured resin coating on a surface thereof, the resin coating consisting essentially of a methyl silicone resin and a methylated melamine resin, the methyl silicone resin including not less than 70% by weight of R--Si--O.sub.1.5 units based on a total content of R--Si--O.sub.1.5 units, R.sub.2 SiO units and R.sub.3 SiO.sub.0.5 units in the methyl silicone resin, wherein R represents a methyl group, and wherein the methylated melamine resin has a weight-average molecular weight of not less than 700.

A two-component electrophotographic developer comprising a toner and a carrier, said carrier including a core material with a resin coating on a surface thereof, the resin coating consisting essentially of a methyl silicone resin and a methylated melamine resin, the methyl silicone resin including not less than 70% by weight of R--Si--O.sub.1.5 units based on a total content of R--Si--O.sub.1.5 units, R.sub.2 SiO units and R.sub.3 SiO.sub.0.5 units in the methyl silicone resin, wherein R represents a methyl group, wherein the methylated melamine resin has a weight-average molecular weight of not less than 700, and wherein the carrier is produced by dissolving or dispersing the methyl silicone resin and the methylated melamine resin in a solvent to thereby form a carrier coating solution, coating the carrier coating solution on the surface of the core material, and curing the resin coating.

An electrophotographic developer comprising:

• a toner containing a coloring agent and a binder resin, said binder resin having an acid value of 3 to 40;
• and
• a carrier, said carrier including a core material with a resin coating layer on a surface thereof, the resin coating layer consisting essentially of a methyl silicone resin and a methylated melamine resin, the methyl silicone resin including not less than 70% by weight of R--Si--O.sub.1.5 units based on a total content of R--Si--O.sub.1.5 units, R.sub.2 SiO units and R.sub.3 SiO.sub.0.5 units in the methyl silicone resin, wherein R represents a methyl group, wherein the methylated melamine resin has a weight-average molecular weight of not less than 700, and wherein the carrier is produced by dissolving or dispersing the methyl silicone resin and the methylated melamine resin in a solvent to thereby form a carrier coating solution, coating the carrier coating solution on the surface of the core material, and curing the resin coating layer.
