    摘要: A toner for electrophotography is provided including a binder resin, a colorant, a charge control agent, and a release agent, wherein a glass transition temperature (Tg) is over 55° C., a molecular weight distribution (MWD) is in the range of about 4.5 to 5.5 when a weight average molecular weight is in the range of about 45,000 to 55,000, and a compression elastic modulus is about 750 MPa or higher at room temperature. Mechanical properties of toner can be obtained at room temperature by controlling rheological properties of toner. The developing properties and fixing properties of toner for electrophotography can be improved by lowering viscosity at a high temperature, and thus image quality can be stabilized.
