PROBLEM TO BE SOLVED: To make fine conductive material pattern possible to be formed on a ceramic base plate by permitting metallic toner adaptable to a conductive pattern with an excellent image property to be stably developed. SOLUTION: This dry system developing method is, allowed to contact develop the metallic toner 4 provided with the average grain size in a range of 2 to 20 μm coating insulating resin on a surface of the metallic particle or the metallic oxide particles, with use of a dry system developing device successively disposing at least, a magnetic transporting member 40, a developing roller 30 and a photoreceptor drum 7, and to control the contact nip width between the developing roller and the photoreceptor drum to the value in a range of 1 to 6 mm. |
