摘要: An electrophotographic toner composition having excellent blocking resistance and offset resistance which contains as a resin binder a polymeric rosin compound having a glass transition temperature of 30.degree. and 100.degree. C. and a gel fraction of 1 to 99% to xylene prepared by the reaction of (a) a glycidyl ester of rosin, (b) a dicarboxylic acid or its anhydride, and (c) a crosslinking agent selected from the group consisting of a polyfunctional epoxy compound, a polycarboxylic acid having a valency of not less than 3 or its anhydride, and a polyhydric alcohol having a valency of not less than 3. A dihydric alcohol may be used in the above reaction in order to improve the low temperature fixing property of the toner.
