METHOD FOR PRODUCING MAGNETIC CARRIER AND MAGNETIC CARRIER PRODUCED USING THE SAME PRODUCTION METHOD

摘要

When a surface of magnetic carrier core particles is coated with coating resin composition particles, the coating is conducted so that a surface of the magnetic carrier is free from cracks and chips and has fewer residual resin composition particles and a coating is uniform. In the method, a rotor having a plurality of stirring members on a surface thereof is rotated to coat the surface of magnetic carrier core particles with the resin composition particles. When the coating is conducted, while repeatedly conducting transportation in a direction of a driver and transportation in an anti-driver direction, the surface of the magnetic carrier core particles is coated with the resin composition. The resin composition particles has a 50% particle diameter (D50) based on volume of 0.2 µm or more to 6.0 µm or less and the proportion of particles of 10.0 µm or more is 2.0% by volume or less.
