Document Type and Number:
Japanese Patent JP2009258234
Kind Code:
A
Abstract:
To provide toner for electrophotography including crystalline polyester and amorphous polyester, having excellent low temperature fixability and storage stability.
This toner for electrophotography includes binder resin. The binder resin includes crystalline polyester and amorphous polyester. When expressing the crystal growth speed in using the toner to a heating retention test by formula (A):G=G0*exp(-E/(R(Th-Tg+50)))*exp(-Ktc/(RTh(Tc-Th))), the generation energy K is 150-400 J/mol, and a factor of the number of crystal nuclei G0 is 10-1,000 sec-1.
