摘要： The present invention relates to novel electrophotographic imaging systems and particularly to novel electrophotographic photoreceptors. These photoreceptors comprise a conductive substrate, an inorganic barrier-charge transport layer, and a photoconductive insulative layer. The barrier charge transport layer comprises aluminum oxide having a non-porous zone adjacent the substrate, and a porous charge transport zone.

摘要： A system and method for conditioning a photoconductive radiation detector achieve charge redistribution within a photoconductive layer without the need for charge removal or charge injection techniques. A first conditioning voltage is applied across the detector to establish a first electric field. The first electric field is reversed relative to fields applied to the detector during image exposure and image read-out operations. While the first conditioning voltage is maintained, the photoconductive layer is exposed for a period of time to first conditioning radiation having one or more wavelengths selected to penetrate at least a portion of the photoconductive layer. A second conditioning voltage, less than the first conditioning voltage, then can be optionally applied across the detector to establish a forward bias electric field. While the second conditioning voltage is maintained, the photoconductive layer is exposed for a period of time to second, broad spectrum conditioning radiation. The detector can then be placed in a dark environment for a period of time, in a shorted condition, to dark-adapt the photoconductive layer.
