Quick Summary

The term "Electrofax" refers to a specific process within the broader field of electrophotography. Electrophotography is a method of image formation that utilizes photoconductive materials. These materials have an electrical resistance that decreases when exposed to light.

The Electrofax process uses photographic paper coated with a dielectric layer. This allows the entire charging, exposure, and development of an image to occur directly on the paper itself. This is a variation of xerography, a widely used technology in document copying machines, where an image is created by selectively discharging a charged surface and then developing it with a pigmented powder.12
