Xerography is a photographic process that uses an electrically charged metal plate to create images. When exposed to light, the electrical charge is neutralized in illuminated areas, leaving a latent image where shadows remain charged. A powdered pigment is then applied, adhering to the charged areas to produce a visible image.
Photographers and print technicians use xerography in photocopying and printing applications to reproduce images quickly and efficiently. Understanding this process is key to appreciating modern dry imaging and reproduction techniques.
