ABSTRACT:
The invention relates to a method of forming composite images. After a first electrostatic latent image of positive image is formed on a photosensitive member, a scorotron charger is used to correct the potential of background area to an intermediate potential. Then a second latent image is formed by exposing a negative image to the intermediate potential. This assures production of composite images of high density and good quality free from fog.
