Abstract
Toner particles having at least one toner resin and at least one polyalkylene wax or a wax having a percent crystallinity of 80% or more are described. The wax that is present in the toner particles has a polydispersity of 2.0 or higher or a percent crystallinity of 80% or more, and also preferably has a number average molecular weight of about 2,000 or higher and/or a melting temperature onset of from about 115° C. to about 130° C. Development systems using the toner particles of the present invention are further described. Also, improvements in various properties associated with development systems are further described such as reduced toner dust levels as well as improved toner image abrasion resistance.
