Abstract
The present disclosure relates to a polyester chemically produced toner composition including a core shell toner particle having special surface features and method to make the same. The special surface features on the outer surface of the core shell toner particle are created by the incorporation of a specially designed polymer latex having styrene and acrylate monomers into the core or shell of the toner particle wherein the polymer latex having styrene and acrylate monomers is tailored to be incompatible with the polyester resin(s) found in the core or the shell of the toner particle.

A chemically prepared toner, comprising:
- a core including a first polyester binder, a pigment, and a wax;
- a borax coupling agent between the outer surface of the core and the shell;
- and
- a shell formed around the core including a second polyester binder and a styrene acrylic latex including a hydrophilic monomer having one of a carboxyl (—COOH) functional group and a hydroxyl (—OH) functional group, wherein the toner has protuberances on its outer surface and the styrene acrylic latex is used to control the raw toner charge and charge distribution of the toner.
