The present invention provides a polyester for toner that is excellent in low-temperature fixability and offset resistance and can reduce in-machine contamination, a method for producing the same, and a toner containing the polyester. A polyester for toner obtained by condensation polymerization of an alcohol component and an alkyl succinic acid having 10 or more carbon atoms and / or a carboxylic acid component containing 0.5 to 50 mol% of an alkenyl succinic acid having 10 or more carbon atoms. A polyester for toner having a detected amount of 6-methyl-2-heptanone and 5-methyl-2-heptanone of 0.5 ppm or less in thermal desorption-gas chromatograph-mass spectrometry, a method for producing the same, and the toner A toner containing polyester.
