    摘要: The method of decreasing unreacted monomer in vinyl polymer of the present invention is a method comprising adding a water-soluble inorganic salt that is able to solubilize unreacted monomer contained in vinyl polymer to an aqueous dispersion in which particles of vinyl polymer are dispersed in an aqueous medium, followed by solubilizing the unreacted monomer and removing the unreacted monomer together with the aqueous medium. According to this method, the amount of unreacted monomer present in a polymer can be efficiently and reliably decreased at low cost without requiring a special apparatus or thermal energy, etc. In addition, the toner resin of the present invention has for its constituent component a vinyl polymer in which the amount of unreacted monomer has been decreased by the method described above. In addition to solving the problem of a foul odor being generated during toner production and fixation when copying, the vinyl polymer obtained according to the method of the present invention also has superior effects such as contributing to improvement of toner characteristics.

    摘要: A toner for developing an electrostatic image is constituted by a composition containing a binder resin component and a coloring agent, wherein the binder resin component contains a low-molecular weight component having a molecular weight of at most 5.times.10.sup.4 and a branching index g' of below 1. The low-molecular weight polymer component is preferably obtained by polymerizing a second monomer in mixture with a prepolymer in the presence of a polymerization initiator comprising a peroxide having a functional group of: ##STR1## and mixed with a high-molecular weight polymer component obtained by polymerization in the presence of a poly-functional polymerization initiator, and a low-molecular weight wax. The resultant toner is characterized by a good balance between the fixability and anti-offset characteristic.
