ABSTRACT:
An electrophotographic toner comprising a binder resin and a colorant, which is used in electrophotographic process employing a flash fixing system for fixation of a transferred toner image, whereinthe binder resin is a polyester resin which partially contains a chloroform-insoluble content; andthe toner contains a polypropylene resin and an ester type structure resin represented by the following formula (I);wherein p, q, m and n each represents a positive integer of 16 to 22 and R may be the same or different and each represents a hydrogen atom or a lower alkyl group having 1 to 4 carbon atoms. The electrophotographic toner is capable of remarkably enhancing the fixation strength of the toner and inhibiting the occurrence of voids during the printing and the occurrence of fuming and odor during the fixation.
