PROBLEM TO BE SOLVED: To provide an electrophotographic toner that obtains good density stability, pulverization properties, and fixability without fogging even using a polylactic acid-based resin which is a biodegradable resin, as a binder resin. SOLUTION: The electrophotographic toner is obtained by melting, kneading, pulverizing, and classifying a raw material which contains at least a polylactic acid-based resin with a number average molecular weight of 5,000-50,000 as a binder resin and a colorant. The crystallinity of the polylactic acid-based resin is 10% or less, more preferably 5% or less. COPYRIGHT: (C)2011,JPO&INPIT
