<p>PROBLEM TO BE SOLVED: To provide a magnetic coated carrier, a two-component developing agent and a developing method by which triboelectric charges are added to a toner in a good state and deposition of the carrier is hardly caused. SOLUTION: This magnetic coated carrier is produced by coating a surface of magnetic carrier core particles containing metal oxide particles with a resin compsn. The magnetic carrier core particles have >=1×10<10>Ω.cm resistivity, while the magnetic coated carrier has >=1×10<12>Ω.cm resistivity. The surface of the magnetic carrier core particle is coated with a coating layer formed by using a resin compsn. which contains a straight silicone resin and a coupling agent. The straight silicone resin contains trifunctional silicone and bifunctional silicone by 100:0 to 40:60 mixing ratio.</p> |
