ABSTRACT:
An electrophotographic toner composition having excellent fixing property at a low temperature, offset resistance, blocking resistance and the like comprising a resin binder and a colorant dispersed in the resin binder wherein the resin binder contains a non-linear polyester resin comprising (a) a dicarboxylic acid as an acid component, (b) a rosin glycidyl ester, an esterificated diphenol and a dihydric alcohol having no phenyl ring as an alcohol component, and (c) a polycarboxylic acid having a valency of not less than 3 and/or a polyhydric alcohol having a valency of not less than 3 as a crosslinking component; the content of the rosin glycidyl ester is 5 to 50% by mole based on the component (b), the content of the etherificated diphenol is 20 to 95% by mole based on the component (b) and the component of the dihydric alcohol having no phenyl ring is 0 to 30% by mole based on the component (b); and the content of the component (c) is 0.5 to 20% by weight based on the polyester resin. A polyvalent metal compound may be used in the above polyester resin in order to improve electric properties in high moisture.
