ABSTRACT:
A method of forming an image comprising the steps of: (a) arranging a plurality of recording electrodes opposite to a movable recording member having an insulating layer on the surface, thereby forming a recording area between the insulating layer and the recording electrodes; (b) supplying to the recording area magnetic toner consisting of toner particles composed of a binder resin and magnetic powder, the toner particles being coated with particles made of a conductive material and further coated thereon with particles made of an insulating material so that it has a bulk resistivity of 10.sup.6 .OMEGA..cm or less and a surface resistivity of 10.sup.5 -10.sup.15 .OMEGA..cm; and (c) applying signal voltage corresponding to the image of the recording electrodes, thereby forming a toner image on the surface of the recording member.
