发明名称 Carrier for electrophotographic developer
摘要 A carrier for developer is disclosed, which is produced by a process including the steps of mixing and heating a carrier material containing a binder resin and a magnetic powder and essentially free of solvent to obtain a molten dispersion of the magnetic powder in the resin; spraying the molten dispersion into droplets; and cooling the droplets to solidify the droplets into carrier particles. The carrier has excellent sphericality, high surface smoothness, and long life when used as a component of a two-component type developer in electrophotography.
