Pressure-fixable microcapsule toner

摘要

A microcapsule toner for pressure fixing, comprising a core material containing a pressure-fixable component and a magnetic material, a first shell layer comprising a formaldehyde copolymer resin and a second shell layer comprising a polymer soluble in an organic solvent provided successively by coating therearound. This microcapsule, since a pressure-fixable core material is successively coated with a lipophobic first shell layer and a lipophilic second shell layer, has well-balanced pressure fixing characteristic and developing characteristic without core material exposed on the surface.
