发明名称 Electrophotographic toner and method of preparing the same
摘要 An electrophotographic toner includes a latex, a colorant, and a release agent, wherein G'(80) is in a range of about 2.0×105 Pa to about 3.0×106 Pa and G'(80)/G'(140) is in a range of about 2.0×102 to about 3.0×103, wherein in regard to a molecular weight distribution on a gel permeation chromatography (GPC) chromatogram, the molecular weight region of 1.0×104 g/mol or less of a tetrahydrofuran (THF)-soluble component of the electrophotographic toner is about 5% or less, and the molecular weight region of 1.0×105 g/mol or more of the THF-soluble component of the electrophotographic toner is in a range of about 5% to about 20%, where G'(80) and G'(140) respectively denote storage moduli of the electrophotographic toner at temperatures of 80° C. and 140° C. when a dynamic viscoelasticity according to a sine-wave vibration is measured at an angular velocity of 6.28 rad/sec and at a temperature increase rate of 2.0° C./min.
