ABSTRACT:
An electrophotographic toner includes a binder resin including a linear polyester such as a polyester formed by condensation of an ethylene oxide adduct of a bisphenole A with a terephthalic acid, and a non-linear polyester such as a polyester formed by condensation of a mixture of an ethylene oxide adduct of a bisphenole A and a glycerin with a terephthalic acid; and, as a magnetic substance, a polyhedral magnetite of not more facets than a hexacosahedron and not less facets than a decahedron. The toner has an excellent fixing property at low temperature, an anti-offset property and a wide fixing latitude.
