Abstract
Pa·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.
