摘要： The present invention is directed to an encapsulated toner for heat-and-pressure fixing whose shell contains a copolymer having one or more acid anhydride groups as the main component. The encapsulated toner of the present invention has excellent offset resistance and fixing ability even at a low fixing temperature, and also it is excellent in blocking resistance. Further, since the resin having a negative charge is used as a shell material, clear images free from background contamination can be stably formed for a large number of copying.
