PROBLEM TO BE SOLVED: To provide a toner for electrostatic image development using a polyester resin obtained without using a tin-based catalyst, having good charging characteristics and color developing property, and capable of low-temperature fixing, a method for manufacturing the same, and an electrostatic image developer and an image forming method using the toner for electrostatic image development. SOLUTION: The toner for electrostatic image development contains an amorphous polyester resin obtained by copolymerizing a group of monomers including at least a polyhydric alcohol component containing a propylene oxide adduct of bisphenol A and a monomer containing a sulfonic acid group in the presence of a titanium catalyst, wherein the proportion of the monomer containing the sulfonic acid group to all the resin is 0.1-20 mol%, and the content of the titanium is 1-1,000 ppm in a mass ratio to the resin. There are also provided the method for manufacturing the toner for electrostatic image development, the electrostatic image developer comprising the toner for electrostatic image development and a carrier, and the image forming method.
