A toner is formed of toner particles each comprising at least a binder resin, a colorant and a wax, and inorganic fine powder. The toner is characterized by (a) containing a sulfur-containing polymer, and (b) showing dielectric loss tangent (tanδ) values at 100 kHz assuming a maximum of 2.5×10 −2 to 8×10 −2 in a temperature range of 100 to 130° C. Because of the combination of the features (a) and (b), the toner can exhibit a good combination of developing performances and fixing performances. |
