PROBLEM TO BE SOLVED: To provide an electrophotographic toner which is free of the problems of proper pulverizability, storage stability, fixability and odor even when a low molecular weight biodegradable resin subjected to hydrolysis treatment is used as a binder resin, and to provide a method for manufacturing the same.SOLUTION: The electrophotographic toner is obtained by adding an acid value adjuster to raw materials including at least a polylactic acid-based resin subjected to hydrolysis treatment so that it becomes a number average molecular weight of ≤20,000 as a binder resin and a colorant and carrying out melting, kneading, pulverization and classification, wherein the amount of the acid value adjuster used is set so that the acid value of the resulting toner is adjusted to be ≤10. |
