Three layered toner for electrophotography

摘要

This invention relates to toner for the development of electrostatic latent images comprising a core particle comprising at least styrene-acrylic copolymers or polyester resins, an intermediate layer coating the core particle and comprising at least styrene-acrylic copolymers, and an outermost surface layer coating the intermediate layer and comprising at least styrene-acrylic copolymers, the contents (%) of the styrenic monomer component in styrene-acrylic copolymers of which the core particles, the intermediate layers and the outermost surface layers are formed being in specified relationships.
