Electrophotographic process utilizing friction charging |
| abstract |
A method for electrostatically charging the surface of a photoconductive insulative layer which is formed by dispersing an inorganic n-type photoconductive powder in a binder, which is primarily a vinyl chloride-vinyl acetate copolymer, which comprises rubbing the insulative layer with a friction material so as to produce a negative charge on the surface of the insulative layer. Representative photoconductors, such as ZnO, and friction materials, such as a cotton velvet cloth, are set out in the specification. A modification of the process entails producing the friction by rubbing the insulative layer while a highly insulative liquid is maintained on its surface. |
