ABSTRACT:
Magnetic carrier particles for electrophotographic developers are coated with a thermoplastic resin by agitating a dry mixture of carrier particles and resin particles in a magnetic field. Thereafter, the mixture is heated to bond the resin to the carrier particles, which then need no further treatment to improve their conductivity prior to use in an electrophotographic developer.
