Abstract
The invention relates to a method of forming monochromatic or dichromatic copy images with use of a developer composed of a high-resistivity magnetic carrier and a nonmagnetic insulating toner which are triboelectrically chargeable. An electrostatic latent image having at least three different levels of potentials is formed and the toner and carrier are adhered respectively onto first and second image portions.
