A magnetic toner employable as a developer for an electrophotographic duplication system, in which an electrostatic latent image is developed on a carrier, a copying sheet is placed over said carrier of developed image, and the developed image is transferred to said sheet, contains magnetic fine particles of an electric resistivity from 10<9> to 10<1><6> OMEGA .cm (at 4000 V/cm DC) and a dielectric constant from 2.6 to 5. |
