Magnetic particles and magnetic carrier for electrophotographic developer

摘要

Magnetic particles of the present invention comprise: magnetic core particles; and a rein composition coat formed on each surface of said magnetic core particles, comprising a metal-based curing agent, a silane-based coupling agent oligomer and a silicone resin, and having an average particle size of 10 to 200 mu m. Such magnetic particles are useful for an electrophotographic magnetic carrier for an electrophotographic developer which have an excellent durability and a stable charging property.
