“…Electrophotographic evaluation o~ Cd(S,Se):Cu.--Although there are other ways of evaluating the surface charge, for example, the revolving turntable (6,7), for this work, we used two Saxon plain paper copying machines (PPC-1) manufactured by Copystatics Manufacturing Corporation, Division of Saxon Industries. Three screens, usually 25 X 10 cm each, were secured to the aluminum drum of the machine and their electrical properties, copying qualities, and maintenance were measured.…”

“…A variant of the xerographic process is to form the image on a photoconductor overcoated with an insulating layer as described above, develop it with toner, and transfer it to paper by conventional means [2]. Several variations of this charge image formation have been proposed [23,72], and one, the Canon NP process, has been used extensively in copiers throughout the 1970s and early 1980s. This process utilizes a photosentive element with a conductive base, a photoconductive layer, e.g., cadmium sulfide in an organic polymer binder, and an insulating top layer.…”

Electrophotography is a copying and printing technique employing electrostatic forces and photoconductivity. Photoreceptor materials include amorphous silicon, organic polymers, and main group alloys. Organic photoconductors have almost entirely displaced traditional photoconductive materials such as selenium alloys. The light sensitivity of modern photoconductors in the near infrared region of radiation is so high that low power inexpensive solid‐state lasers are used as light sources for digital imaging. Developer materials and the development process are discussed. Toner triboelectrification and the ability to control the uniformity of toner charge have progressed to the point that stable, reliable operation is achieved over a broad range of environmental conditions. Electrophotographic image quality, even in color, is approaching that of lithographic images. The roles of carrier materials, imaging media, and fusing are defined.
