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 t…
