ABSTRACT:
A method for producing an encapsulated toner for heat-and-pressure fixing including the step of forming a heat-fusible core material containing at least a thermoplastic resin and a shell, the shell being formed so as to coat surfaces of the heat-fusible core material with an amorphous polyester by in situ polymerization. In this method, a pH of a suspension during polymerization is adjusted to a range of 9 to 13, and an acid value of the amorphous polyester is from 0.1 to 15 KOH mg/g.
