Abstract
A copying apparatus for synthesizing two images on one piece of copying paper. The apparatus includes a photosensitive body having a photosensitive surface, first and second light exposure assemblies disposed in spaced-apart relationship with respect to the path of rotation of the photosensitive surface and an image development assembly. In the first light exposure assembly, a first original positive image source controls light emitted from a first light source which light is transmitted to the photosensitive surface to create a first latent image of the information in the first original positive image source on a first portion of the photosensitive surface. No latent image is formed in the remainder or second portion of the photosensitive surface. In the second light exposure assembly, a second original positive image source controls light from a second light source, which light is transmitted to the photosensitive surface to form on at least a part of the second portion of the photosensitive surface a second latent image of the information in the second positive image source and to change the electric potential of the first portion of the photosensitive surface corresponding to the first latent image to the same electric potential as the second latent image portion. The photosensitive surface then passes the image development assembly in which toner adheres to the portions of the photosensitive surface on which the latent images have been formed but does not adhere to the portion of the photosensitive surface in which no latent image has been formed, thereby making the portion corresponding to the first and second latent images visible. The visible images are thereafter transferred to a piece of copying paper.
