Abstract
There is disclosed a color xerographic printing system which utilizes a full length developer to develop a first latent image and registration marks on the margins along the first latent image. The color printing system of this invention, also utilizes two margin chargers prior to a second developer. Each one of the margin chargers restores the charge under the developed registration marks to prevent the registration marks from attracting more toner.
