TONER AND TWO-COMPONENT DEVELOPER Russian patent published in 2017 - IPC G03G9/08 

FIELD: printing industry.

SUBSTANCE: (i) the toner including at least a coloring agent, a polymer, and a parting agent is proposed. Spin-spin relaxation time (t₂) of the toner at 90°C obtained by means of the Hahn's spin echo in the analysis by the method of impulse NMR is from 1.80 ms to 7.00 ms. Furthermore, (ii) the toner is proposed according to the paragraph (i). Spin-spin relaxation time (t₂) of the toner at 90°C obtained by means of the Hahn's spin echo in the analysis by the method of impulse NMR is from 3.80 ms to 5.90 ms.

EFFECT: provision of the possibility for creation of a toner, which is able to provide perfect low-temperature holding power and reproducibility of color, as well as to show perfect thermal stability during storage.
