Imaging Systems for Fast Eletrophotographic Processes

摘要

Image carriers based on amorphous Se-alloys and inorganic-organic multilayer systems were developed for applications in fast electrophotographic processing. The combination of Se photoconductive layers doped with 0.5%. As or up to 15% Te with a strain reducing metallic interlayer on a flexible endless Ni-belt is demonstrated to provide the photographical quality and bending strength required by fast reprography. The addition of Te is shown to significantly extend the spectral sensitivity range. Thin flexible foils and belts can also be made out of multilayered systems using Se-alloys and polyrinylcabazole. It is expected that it will be possible to extend the spectral sensitivity to the near infrared, thereby opening a new era of applications in communication and information systems.
