Abstract:
There is provided a toner for electrophotography containing at least a binder resin, a colorant and a barium compound, and having a relaxation modulus G(t) of from about 2.0×102 Pa to about 3.0×103 Pa in a relaxation time of t=10×Dt (wherein Dt is the heating time taken during fixing) as determined by the measurement of dynamic viscoelasticity, and a barium content of from about 0.1% to about 0.5% with respect to the total amount of constituent atoms in the toner as determined by X-ray fluorescence.
