<p>PURPOSE:To obtain an electrophotographic toner being excellent in fixing ability at low temp., offset resistance and blocking resistance. CONSTITUTION:In a electrophotographic toner containing a binder resin composed essentially of a nonlinear polyester resin and a colorant, the nonlinear polyester resin is obtained by polycondensating using (A) at least a kind of compound selected from a group of bivalent carboxylic acid, its acid anhydride and lower alkyl ester as an acid compound, (B) a glycidyl ester of tert. synthetic fatty acid having 6-20 carbon number and etherified diphenoles as diol component and (c) an aromatic polycarboxylic acids as a crosslinking agent to manufacture the electrophotographic toner.</p> |
