TONER Russian patent published in 2015 - IPC G03G9/08 G03G9/87 

FIELD: printing.

SUBSTANCE: invention relates to a toner. The toner has toner particles each of which comprises binding polymeric resin, wax, and inorganic fine particles. Specific surface area of the inorganic fine particles is in the range from 10 to 60 m²/g. The binding polymeric resin is polyester resin. Wax is paraffin wax or Fischer-Tropsch wax and has a peak temperature of the maximum endothermic peak of 66 to 110°C on the endothermic curve with increasing temperature measured using differential scanning calorimeter in the temperature range from 30 to 200°C. The inorganic fine particles are fixed on the surface of the toner particles as a result of surface treatment with hot air.

EFFECT: obtaining toner which satisfies the charge stability, the possibility of appearance at low temperature, which provides image gloss, and resistance to rolling during fixation.
