    摘要： An electrophotographic developer comprising a toner and a carrier, in which the carrier is provided on the surface of a core material thereof with a resin coating layer comprising a cured body of a methyl silicone resin containing not less than 70% of T-unit and a methylated melamine resin having molecular weight of not less than 700. This developer is not lowered in flowability, generates no spent particles and presents stable electric charging characteristics. Accordingly, the developer of the present invention is suitably used where there is used a toner containing no electric charge controlling agent.

    摘要： A resin-coated magnetic carrier for two-component developers which comprises magnetic particles and a resin coating formed on the individual magnetic particles is described. The resin coating is made of a cured resin composition comprised of an alkylated melamine resin whose molecular weight satisfies the following inequality
    M ≧ 1100C - 400
    wherein M represents a weight average molecular weight of the resin and C represents the number of carbon atoms in the alkyl moiety, and an acryl-modified silicone resin. The use of the composition is effective in preventing the coated particles from melt adhesion and in forming a smooth and uniform coating layer on individual particles. The resin-coated carrier is significantly reduced in amount of spend carrier and has good durability, moisture resistance, chargeability.
