Encapsulated electrostatic toner with locally attached non-magnetic inorganic particles

摘要

An encapsulated toner for development of electrical latent images comprises a core particle containing a colorant and a soft solid material, inorganic fine particles attached to the vicinity of the surface of the core particle, and a shell coating the core particle and the inorganic fine particles. The inorganic fine particles function to, e.g., reinforce the encapsulated toner with a thin shell and may be attached to the core particles through dry-mixing. The core particles with the attached inorganic particles may be coated with a shell resin through phase separation.
