    摘要: A toner process comprised of a first heating of a mixture of an acicular magnetite dispersion, a colorant dispersion, a wax dispersion, and a core latex comprised of a first latex containing a vinyl crystalline polyester resin substantially free of crosslinking, and wherein said polyester is substantially dissolved in a vinyl monomer and polymerized to provide said first core latex resin, and which mixture contains a second crosslinked resin containing latex wherein said heating is accomplished in the presence of a coagulant to provide aggregates; adding a shell latex comprised of a polymer substantially free of crosslinking, and further heating said aggregates to provide coalesced toner particles, and wherein said further heating is at a higher temperature than said first heating.
