Abstract
An electrophotographic toner composition is disclosed, including toner particles containing a coloring agent, a binder resin and at least two kinds of additives, wherein these additives satisfy the relationship, 4<((.di-elect cons..sub.H -.di-elect cons..sub.L)/0.75+log(f))<16, in which f in Hz corresponds to a 1 kHz frequency used for the present dielectric constant measurements, and .di-elect cons..sub.H and .di-elect cons..sub.L are respectively highest and lowest values of dielectric constants obtained at 1 kHz for the additives.
