Abstract
Waste toner is fused and kneaded with modified polyphenylene ether so as to be used as a molding material. The waste toner preferably includes a toner ingredient including styrene-acrylic resins. With this arrangement, it is possible to inexpensively manufacture a molding product which has excellent physical properties such as tensile strength, flexural rigidity, and flexural strength and is usable for various purposes.
