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.
