摘要： 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.

摘要： A method for nonmagnetic monocomponent development is intended for use in an electrophotographic copying machine or electrophotographic printer and is capable of producing highly durable prints of high quality during continuous printing operations. In the nonmagnetic monocomponent development, a developer is transported by a development roller to a photoconductor drum. A Doctor blade triboelectrifies the developer and simultaneously regulates the thickness of a layer of the developer. As the developer, a toner is used, which toner is produced by coagulating minute particles having a diameter between 0.1 and 3.0 .mu.m and then heating the minute particles, thereby thermally fusing these particles.

摘要： Toner magnetic powder which uses a resin as a binder and contains a dye is coated by a methyl methacrylate resin, thereby forming a carrier. A developer is formed by such a carrier in which those two components are mixed. An electric conductivity of the impurity extracted water of the carrier due to the pressurization in the pure water is set to 60 .mu.S/cm or less. Namely, the purity is improved so that the electric conductivity of the impurity extracted water of the methyl methacrylate resin due to the pressurization in the pure water is set to 20 .mu.S/cm or less, and the purity is improved so that the electric conductivity of the impurity extracted water of the magnetic powder due to the pressurization in the pure water is set to 60 .mu.S/cm or less, thereby forming a carrier. A carbon addition amount upon manufacturing of the carrier is controlled so that the electric resistance of the carrier is set to a value within a range of 1.times.10.sup.4 to 1.times.10.sup.8 .OMEGA.cm. Further, a carbon addition amount upon manufacturing of the toner is limited so that the electric resisance of the toner is set to 1.times.10.sup.11 .OMEGA.cm or more.
