PROBLEM TO BE SOLVED: To provide a toner wax reducing bleed out to the surface layer of a toner particle and having excellent fixability and storage property. SOLUTION: The toner wax composition for a polyester resin comprises fatty acid esters (A) and (B) expressed by formula (1) and formula (2), respectively, mixed in a weight ratio (A):(B) of 30:70 to 70:30. In formula (1), R<SP>1</SP>represents a straight-chain saturated alkyl group having 14 to 26 carbon atoms; and R<SP>2</SP>represents a straight-chain saturated alkyl group having 13 to 25 carbon atoms. In formula (2), R<SP>3</SP>represents a neopentyl polyol residue having a valence of 2 to 8; R<SP>4</SP>represents a straight-chain saturated alkyl group having 13 to 25 carbon atoms; and m is an integer of 2 to 8.
