Abstract
An electrification enhancer is either contained in the photoconductor, is present as a coating on the surface thereof, or is applied prior to use. A compound such as ammonium fluoride, a ferroelectric substance, a high molecular substance (fluorine resin) with an equivalent work function of 4.10 or greater, etc. are effective. The chargeability of the photoconductor is improved. The construction is best suited for the rear photorecording process, but is also effective in other types of contact charging recording systems.
