n.A process that forms images using the photoelectric properties of sensitive substances.


Electrophotography includes electrostatic (xerographic), dielectric paper, electroplastic, and persistent internal polarization processes. It has been used for microfilm that can be updated, allowing new images to be added after creation or existing images to be overwritten with new images.The dielectric paper process uses paper coated with a photoconductive pigment in a binder resin. The electro-plastic process uses a plastic film coated with a photoconductive layer; exposure to light causes a stress in the plastic and, when heated, the plastic deforms to reveal the image.
