By controlling the migration to the toner particle surface of the crystalline polyester present in the toner particle, a toner is provided that exhibits an excellent durability in long-term use, a stable charging performance after holding in a high-temperature, high-humidity environment, and an excellent low-temperature fixability, in which the toner having a toner particle that contains an amorphous resin, a crystalline polyester, and a wax, wherein the toner particle includes, at the surface thereof, a coat layer containing a cyclic polyolefin resin.

The present disclosure relates generally to a method to make a chemically prepared toner that employs a crash cooling process. In particular, the crash cooling process involves the addition of a toner slurry having a temperature between 70 C. and 90 C. to an equivalent amount of cold water having a temperature between 5 C. and 20 C. Polyester and styrene acrylic toners as well as polyester core shell toners having a borax coupling agent between the toner core and toner shell made from this cooling process results in an improvement to the amount of toner waste, thereby achieving a higher toner usage efficiency for an electrophotographic printing system.
