AbstractElectrophotographic images are formed by the displacement of matter in electric fields: the deposition of charged particles or the deformation of a plastic surface is controlled by a geometric field pattern, configured by the photo‐response of a photoconductive insulating material. Image amplification up to 105may be achieved by the application

Electrorheological Toners for Electrophotography
Journal of Colloid and Interface Science, 2002The electrorheological (ER) behavior of pigment suspensions dispersed in a nonaqueous solvent was examined for their application as liquid toners for electrophotography. In electric fields, particles can align into chains along the field vector by dielectric polarization forces and the suspensions undergo a rapid transition from Newtonian fluids to ...

Proceedings of the IEEE, 1972
This review is concerned primarily with the electrophotographic systems currently in use, i.e., the electrodeless stored energy systems. First, the history of reproduction is traced from printing, through wet- and dry-chemical photography, to electrophotographic systems. The electrodeless system is defined and described in terms of the processing. Then,

Reviews of Modern Physics, 1993
Electrophotography is one means of arranging 100 million pigmented plastic particles on a sheet of paper to faithfully replicate an original. It is based on many diverse phenomena and employs many properties of matter. These include gaseous ionization in the charging step; photogeneration and charge transport through disordered solid-state materials in

Photoconductors In Electrophotography
SPIE Proceedings, 1986In xerography, a corona charged photoconductor film transforms an optical image into an electrostatic image that is subsequently developed. A variety of photoconductor materials has been employed in commercial reproduction machines. These include alloys of amorphous selenium with arsenic and tellurium, zinc oxide, and cadmium sulfide particles in ...

We review the recent advances in the use of laser sources in the field of electrophotography. New experimental investigations of the photogeneration and transport processes utilized in electrophotography are now possible because of the short pulse duration, high peak power, high collimation, monochromaticity, and/or coherence of a laser source.

Physics Today, 1986
Electrophotographic printing and copying systems are based on two wellknown but not well-understood physical phenomena: electrostatic charging and photoconductivity. That some materials can acquire an electric charge by contact or rubbing has been known at least since the time of Thales of Miletus, around 600 B.C., and much work has been done on ...
