An electrophotographic toner having a core-shell structure including a crystalline resin in its core region or a sea-island structure including a crystalline resin in its island region, wherein the toner has 1) a resistance of 5.0×10 12 Ω·cm or higher, 2) a dynamic viscosity coefficient of 3×10 3 Pa·s or higher at a temperature which is 50° C. higher than a melting point of the crystalline resin, and 3) a dynamic viscosity coefficient of 1×10 5 Pa·s or lower at a temperature which is 10° C. higher than the melting point of the crystalline resin. |
