Procedure

13 Parts of the above-obtained polymer resin having a higher molecular weight and 100 parts of xylene were charged into a flask, and dissolved. The inner atmosphere of the flask was replaced with nitrogen gas, and the mixture was heated up to the boiling point of xylene. While the mixture was stirred under the reflux of xylene, a mixture containing 73.5 parts of styrene, 13.5 parts of n-butyl acrylate and 3.3 parts of benzoyl peroxide (polymerization initiator) were dropwise added over 2 hours to carry out a solution polymerization. After the addition was completed, the reaction mixture was aged for 1 hour with stirring under the reflux of xylene, to give a styrene/acrylate copolymer resin having molecular weight maximal values, measured by GPC, of 5,000 and 2.0×106 and containing 13% by weight of the polymer having a higher molecular weight, for use in an electrophotographic toner of the present invention.
