In an imaging system a thin polyweb 11 is brought against randomly disposed spacers ll-on the surface of a photoconduc-tor 10, thereby maintaining an air gap A of 4 to 16 microns between the web and surface- Thereafter the outer surface 14 of the web is charged with a corotron 15 and means 16 irnagewise expose the web, whereby air in the gap is ionized and provides a latent image on the inner side of the web 17. The image bearing web is guided away from the photoconductor by a biased roller 18, a bias in the range of 200 to 300 volts being pro-vided to avoid image deterioration. Subsequently, the web is positioned in intimate contact with roller 18 and a biased gravure development roller 19, roller 19 being biased with 200 to 300 volts, Thereafter, the web is separated from roller 18 but remains against roller 19, whereby the latent image on the web is developed. The developed image is transferred to a paper 24. A light 12 is used to clean the photoconductor.
