ABSTRACT:
A copying apparatus operable with an original having an image-bearing surface on which images to be reproduced are supported. A radiation reflected by the image bearing surface is focused on a photosensitive paper, by a self-focusing lens array, so that latent images corresponding to the images on the image-bearing surface are formed on the photosensitive paper. The latent images are developed into visible images by a developing device such as a device adapted to apply a pressure to the photosensitive paper. The photosensitive paper may be a self-activated type having a photosensitive material and a developer material which chemically react with each other in the developing process. Alternatively, a separate developer paper having a developer material is superposed on a photosensitive paper having only a photosensitive material. In this case, the photosensitive and developer papers are superposed on each other for development of the latent images due to the chemical reaction between the photosensitive and developer materials. After the development, the two papers are separated from each other by a separating device such as a roller separator.
