Patent ID: 7833688

Claim:
A method for reducing toner plasticization in a toner, comprising forming a toner composition by mixing a resin and a colorant, the resin comprising a mixture of crystalline polyester resin and amorphous polyester resin, wherein the amorphous polyester resin comprises a partially crosslinked amorphous polyester resin; adding and mixing a wax into the toner composition to increase the dispersion of the crystalline polyester resin and the amorphous polyester resin, wherein the wax comprises carnauba wax and the mixing is accomplished in an extruder at a temperature of from about 80° C. to about 120° C.; and grinding and classifying the toner composition to form a toner having a higher glass transition temperature than a toner without the carnauba wax, wherein the toner without the carnauba wax is prepared according to the same method as described for said toner but without the addition of a wax comprising carnauba wax.
