FIELD: chemistry.
SUBSTANCE: disclosed is toner for developing an electrostatic image, wherein toner particles contain a non-crystalline resin and a crystalline resin, where the crystalline resin contains a polyester resin C, having in the backbone chain a urethane bond a carbamide bond, or both, and the non-crystalline resin contains a polyester resin with peak molecular weight of 1000-30000, and where each toner particle has the shape of an islet in a continuous phase, wherein resin C is dispersed in the non-crystalline resin on the cross-section of the toner particle. The invention also discloses a developer and an image forming device comprising said toner.
EFFECT: disclosed toner has excellent low-temperature fixation capacity, resistance to hot displacement and stable heat resistance during storage.
