Abstract:
1. An electrophotographic toner comprising a latex, a colorant, and a releasing agent, wherein the electrophotographic toner comprises silicon (Si) and iron (Fe), each of the Si and Fe is in the range of about 3 to about 1,000 ppm, a mole ratio of Si to Fe (Si/Fe) is in the range of about 0.1 to about 5, an initiation temperature of a maximum heat absorption peak curve when a temperature increases in a heat absorption curve of the toner measured by a differential scanning calorimeter (DSC) is in the range of about 68 to about 89° C., and a peak temperature of the maximum heat absorption peak curve is in the range of about 86 to about 89° C., and wherein the releasing agent comprises 100 parts by weight of a paraffin-based wax and about 12.5 to about 50 parts by weight of an ester-based wax.
