摘要： A process for producing a toner by subjecting a polymer and a resin component containing a cross-linkable polymer capable of cross-linkingly reacting with the polymer, to cross-linking reaction in the presence of a first wax to form a wax-containing cross-linked polymer composition; mixing the wax-containing cross-linked polymer composition with at least a colorant and a second wax, followed by melt-kneading to form a toner composition; and pulverizing the toner composition to produce toner particles. Also disclosed is a toner produced by this process. The toner thus obtained is a toner whose fixing performance and anti-offset properties are well balanced and also which makes it possible to afford images having less fog and high quality, over a long period of time in environments of from low temperature and low humidity to high temperature and high humidity, and is highly durable without causing any contamination of members with which the toner comes into contact.
