Abstract
An electrostatic imaging process uses either a moving belt or a rotating drum with an insulative or dielectric layer backed by a conductive layer. A matrix of writing styli are used to charge the dielectric layer which are ionized air jets. After the image is developed by a toner, the toner is heated so that it will be concurrently transferred and fixed to the paper sheet.
