PROBLEM TO BE SOLVED: To provide an electrophotographic toner excellent in both low-temperature fixability and storage stability, and to provide a method for manufacturing the same. SOLUTION: The electrophotographic toner includes a crystalline polyester, an amorphous polyester, a colorant and a crystal-nucleation agent, 2Θof wide-angle X-ray diffraction of which has a peak within a range of 14-26°, wherein the crystal-nucleation agent is at least one selected from the group consisting of a crystal-nucleation agent (A): a fatty acid amide whose melting point is from the melting point of the crystalline polyester to (the melting point)+100°C, a crystal-nucleation agent (B): a quinacridone compound whose average particle diameter is 1-200 nm, and a crystal-nucleation agent (C): a compound whose solubility in at least one alcohol having a content of≥20 mol% in alcohol components as raw material monomers of the crystalline polyester is≥0.2 wt.% at 50°C, and whose melting point is (the melting point of the crystalline polyester)+5°C or above (but the compound is neither fatty acid amide nor quinacridone compound).
