ABSTRACT:
The present invention is directed to an encapsulated toner for heat-and-pressure fixing having a heat-fusible core material containing at least a thermoplastic resin and a coloring agent and a shell formed thereon so as to cover the surface of the core material. An amorphous polyester is used as the main component of the shell, and the amount of the amorphous polyester is normally 3 to 50 parts by weight, based on 100 parts by weight of the core material. The encapsulated toner of the present invention is excellent in offset resistance, fixable even at a low temperature and excellent in blocking resistance when it is used for heat-and-pressure fixing using a heat roller.
