ABSTRACT:
A toner for electrophotography is provided that includes a binder resin, a colorant, a charge control agent, and a releasing agent, wherein the toner has a complex viscosity (η) of about 4.0×101Pa·s to about 1.6×103Pa·s at a temperature ranging from about 40° C. lower than a toner fixing temperature to about 10° C. higher than the toner fixing temperature and has a specified activation energy of 15 to 85 KJ/mol. By defining viscosity dependency in a linear modulus region of a toner and comprehensively defining thermal and rheological properties with respect to fixing conditions, a fixing phenomenon can be generalized and the quality of a toner can be evaluated.
