Lasers in Electrophotography

We review the recent advances in the use of laser sources in the field of electrophotography. New experimental investigations of the photogeneration and transport processes utilized in electrophotography are now possible because of the short pulse duration, high peak power, high collimation, monochromaticity, and/or coherence of a laser source. Also, the increasing availability of reliable and inexpensive lasers has resulted in many new technological uses of lasers in electrophotographic applications. In addition to the continued use of HeNe and HeCd lasers, new products have been configured with GaAs lasers.
