Abstract:
An electrophotographic toner which is excellent in grindability, fixing property and durability by being obtained via a step of melt-kneading a mixture containing an amorphous bioplastic having a weight-average molecular weight (Mw) of 55000 to 120000, a terpene phenol resin, and a styrene acrylic resin having a weight-average molecular weight (Mw) of 85500 to 118000 so as to obtain a kneaded mixture, and a step of grinding the kneaded mixture after hardening.
