ABSTRACT:
An electrostatic image developing toner comprising a non-crystalline polyester resin, wherein the non-crystalline polyester resin is obtained by copolymerizing monomers in the presence of a titanium catalyst; the monomers comprise a polyhydric alcohol component and a monomer containing a sulfonic acid group, the polyhydric alcohol component comprises a propylene oxide adduct of bisphenol A, a ratio of an amount of the monomer containing a sulfonic acid group to the total amount of the non-crystalline polyester resin is 0.1 mol % to 20 mol %, and a content of titanium is 1 ppm to 1000 ppm by weight based on the amount of the resin. The invention also provides a method for producing the same, an electrostatic image developer and image forming method using the toner.
