ABSTRACT:
An electrophotographic printer develops a toned image directly on a sheet of conventional paper, such as bond paper, without first forming the toned image on a layer of photoconductive material. The sheet of conductive paper is ordinarily electric conductive, owing to its relatively high moisture content. Therefore, prior to positioning the sheet of paper adjacent the layer of photoconductive material, the sheet of paper is first dried by heating to a temperature sufficient to evaporate the moisture content therein to a level of less than 3% by weight of the conventional paper. Once the sheet of conventional paper is dried, it is inserted between a developer and the layer photoconductive material so that toner particles attracted to a latent image on the layer of photoconductive material are intercepted by the dried sheet of conventional paper.
