TONER, DEVELOPER, IMAGE FORMING DEVICE AND PROCESS CARTRIDGE Russian patent published in 2016 - IPC G03G9/87 

FIELD: printing.

SUBSTANCE: present invention relates to toner, developer, image forming device and a process cartridge. Disclosed group of inventions includes a toner, developer and image forming apparatus. Toner contains resin binder, which contains crystalline resin, wherein toner has maximum temperature (P1) of endothermic peak from 50 °C to 80 °C and total amount of (Q) of absorbed heat from 35 J/g to 90 J/g at a first temperature increase during differential scanning calorimetry and wherein ratio (Q_p/Q) of total amount of (Q_p) absorbed heat of toner in temperature range from 20 °C to maximum temperature (P1) of endothermic peak to total amount (Q) of absorbed heat of toner is 0.65 to 0.83.

EFFECT: technical result consists in providing toner which has excellent fixation at low temperature and heat resistance during storage and may suppress sticking of toner particles sticking in developing device.
