Abstract
PURPOSE: To accomplish the copying operation of multiple colors in the system, in which the developing powders are transferred to a magnet roll by a magnetic force, by arranging a magnetic pole portion to face an electrostatic latent image, during the developing operation, but a non-magnetic pole portion to face the same during the non-developing operation.
