Abstract

PURPOSE: To make possible good repetitive development processing without performing cleaning by making the attraction forces of the carrier and toner forming magnetic brush at the values of a specified range.
CONSTITUTION: The latent images having been formed on a photosensitive drum 1 are developed with a developing device 4 and are then copied onto copying paper 6. Upon finishing of this first copying, the excess toner at which image density becomes 0.4 or under remains on the surface of the drum 1. Next, the drum 1 is charged to specified potentials according to the existing and non-existing regions of the residual toner through uniform exposure with the specified uniform charging exposure device 3 of a charger 2. If the toner attraction force of the carriers forming the magnetic brush of specified densities by the subsequent device 4 is made larger than the adhesion force of the excess toner on the drum 1, the latent images are well repetitively developed by the magnetic brush of the excess toner attracted to the carrer without undergoing cleaning.
