| titleOfInvention | Method for producing toner for developing electrostatic image |
| abstract | To provide a method for producing a toner for developing an electrostatic image capable of ensuring low-temperature fixability, improving heat-resistant storage stability and achieving high image quality. SOLUTION: A crystalline resin particle and an amorphous resin particle containing a vinyl resin as a main component in an aqueous medium are heated to a temperature equal to or higher than the melting point of the crystalline resin, and agglomerated and fused to form core particles. A first step of obtaining a dispersion, and amorphous polyester resin particles containing a structural unit derived from a bisphenol A propylene oxide adduct and a structural unit derived from a bisphenol A ethylene oxide adduct in the obtained dispersion. And a second step of forming a shell layer on the surface of the core particles at a temperature equal to or higher than the recrystallization temperature (Rc) of the crystalline resin and obtaining a dispersion containing particles having a core-shell structure, A third step of cooling the obtained dispersion to a temperature below Rc−25 ° C. and a fourth step of maintaining the obtained dispersion in the specific temperature range T1 for 30 minutes or more.
