(57) [Problem] To provide a binder for producing a toner having excellent low-temperature fixability and offset resistance, and a toner for developing an electrostatic image containing the binder. Kind Code: A1 A raw material monomer mixture (a) of two polymerization systems each having an independent reaction path, a compound (b) capable of reacting with any of the two raw material monomers of a polymerization system, and a release agent (c) And a binder obtained by performing the two polymerization reactions in the same reaction vessel, and a toner for developing an electrostatic charge image, comprising the binder. |
