摘要:
A process for producing a core-shell toner is provided in which the toner has core particles containing at least a binder resin (1), a colorant and a release agent and shell layers which contain at least a resin (2) and with which the core particles are covered; and the process including the steps of (A) mixing a binder resin-(1) dispersion, a colorant dispersion and a release agent dispersion, (B) adding to a mixed dispersion thus obtained an agglomerating agent to effect agglomeration, (C) adding to core agglomerated particles thus formed a mixture prepared by mixing the resin-(2) dispersion and a metal salt to make the resin (2) adhere to the surfaces of the core agglomerated particles, and (D) heating core-shell agglomerated particles thus formed to a temperature not lower than the glass transition temperatures of the binder resin (1) and resin (2) to effect fusion thereof.
