<p>PROBLEM TO BE SOLVED: To obviate the occurrence of toner spent, filming and sticking, to improve the preservable property of a material to be printed and to obtain good pulverizing processability by making the energy saving by lowering of a fixing temperature to a temperature lower than heretofore possible and making the preservable property better than with toners using the conventional low melting point resins and averting the occurrence of a change of the interaction with external additives with lapse of time. SOLUTION: Electrophotographic toners are prepared by using cyclic butadiene for a main binder.</p> |
