Definitions

  • Selenium is preferably used for the photosensitive layers of recording media because it is good. photoconductive properties but poor conductivity in the dark. Both properties are important for the workflow of photocopiers or other devices that work with photoelectric recording media. This is because the recording medium is initially charged on its surface in the dark. When using selenium, positive charging takes place. Because of the low dark conductivity of the selenium, this charge persists over longer tents. When imaging with image information, however, pairs of charge carriers are then generated in the selenium, which lead to the local unloading of the surface. The surface charge image is developed with a toner and the image thus held on the recording medium is transferred to paper or another recording end medium. The surface charge pattern of the recording medium is then removed by exposing its entire surface and toner still present on the surface is wiped off. Then the record carrier is available for a new loading and thus a new copying process.
