PURPOSE:To obtain stable running characteristics and good images without offset phenomena by making the difference between the softening point and softening initiating temp. of a magnetic toner >=5 deg.C. CONSTITUTION:A magnetic material, binder resin and conductive material are used as essential components and the difference between the softening temp. and softening initiating temp. of the magnetic toner is made >=5 deg.C. More preferably, the magnetic toner of which the electric conductivity is 10<-4>-10<-12> mho/cm in 1,000V/cm DC electric field is used. |
