An individual inventor, Chester Carlson, conceived the idea of Xerography. This is a new photographic process which in a relatively short time has found numerous industrial applications. It is completely dry and is based entirely upon principles of photoconductivity and electrostatics. The process

‘employs a plate which consists of a thin photoconductive coating on a metallic sheet. This coating can be electrically charged in the dark and will hold this charge until exposed to light. Thus an electrostatic image can be produced on the plate by exposing the plate to an optical image. When the plate is dusted with powder particles, the electrostatic image is transformed into a powder image which can be transferred to paper and fixed by fusing.’1
