摘要:
An electrophotographic photoreceptor is prepared for charging. Corona electrodes before and after the erase lamp apply respective biases to provide the correct sign of charge for cleaning, and to discharged trapped charges in the photoreceptor. Toner is then cleaned off the photoreceptor. This leaves the photoreceptor electrically and mechanically reconditioned and ready for its next printing cycle.
摘要:
Apparatus for electrically reconditioning a rotatable photoreceptor in an electrophotographic (EP) printer includes a charger, an exposure subsystem, a transfer station, and an erase lamp arranged in that order around the photoreceptor in the direction of rotation thereof. A first corona electrode is disposed within 3 cm of the surface of the photoreceptor, but not in contact therewith, between the transfer station and the erase lamp. The transfer station and the erase lamp are at most 1 cm apart. A second corona electrode is disposed within 3 cm of the surface of the photoreceptor, but not in contact therewith, after the erase lamp in the direction of rotation of the photoreceptor. The erase lamp and the second corona electrode are less than 1 cm apart.

摘要:
An x-ray detector, detection assembly, and method of using the detector and detection assembly. The detector is used with an x-ray source and has a converter including a mass of prompt emitting radiographic phosphor particles and a photoconductive binder. The mass of particles is dispersed and embedded in the binder. The phosphor absorbs x-rays emitted by the source and emits longer wavelength actinic radiation responsive to the x-rays. The photoconductive binder absorbs the actinic radiation and produces electron-hole pairs responsive to the actinic radiation.

Glassy solid electrolytes and charge transporting elements including antistatic elements and charge generating elements. The charge generating element has an electrically conductive layer, a charge generating layer overlying the electrically conductive layer, and a layer of glassy solid electrolyte overlying the electrically conductive layer. The glassy solid electrolyte includes a complex of silsesquioxane and a charge carrier. The complex has a surface resistivity from about 1.times.10.sup.10 to about 1.times.10.sup.17 ohms/sq. The complex has a T.sup.2 -silicon:T.sup.3 -silicon ratio of less than 1 to 1. The complex has a ratio of carbon atoms to silicon atoms of greater than about 1.2 to 1.
摘要:
An electrophotographic element comprises: an electrically conducting layer, a charge generating layer overlying the electrically conducting layer, and a charge transport layer overlying the electrically conducting layer. The charge transport layer, which can be an overcoat overlying the charge generating layer, comprises the reaction product in an aqueous medium of a mixture comprising a silsesquioxane polymer and a hole transport compound that comprises a tertiary arylamine containing at least one alcoholic or one phenolic hydroxy substituent.
