摘要： An apparatus for applying an electrical charge to a charge retentive surface, wherein a bias contact roll member is situated in contact with a surface of the photoreceptor. The bias contact roll member is supplied with an electrical bias including an oscillating voltage signal having a DC offset, wherein the oscillating voltage is clipped via a rectifier circuit to remove a predetermined polarity component thereof.

摘要： An apparatus which develops a latent image recorded on an image receiving member with developer material. A donor roll is positioned in a chamber of a housing having a supply of developer material. The donor roll transports a metered layer of developer material into contact with the latent image to develop the latent image. A conductive brush includes bristles having a diameter from about 6 to about 20 microns and contacts the metered layer of developer material on the developer roll. This substantially prevents the variation of triboelectric charge on the developer material on the donor roll so as to create a uniform charge level on the development material layer for development of the latent image.
摘要翻译：一种用显影剂材料显影记录在图像接收部件上的潜像的装置。供体辊定位在具有显影剂材料供应的壳体的室中。供体辊将计量的显影剂材料层与潜像接触以显影潜像。导电刷包括具有约6至约20微米直径的刷毛，并与显影剂辊上的显影剂材料的计量层接触。这基本上防止了供体辊上的显影剂材料上的摩擦电荷的变化，从而在显影材料层上形成均匀的电荷水平，用于显影潜像。

摘要： An electrophotographic imaging member including a supporting substrate coated with at least a charge generating layer, a charge transport layer and an overcoating layer, said overcoating layer comprising a dihydroxy arylamine dissolved or molecularly dispersed in a crosslinked polyamide matrix. The overcoating layer is formed by crosslinking a crosslinkable coating composition including a polyamide containing methoxy methyl groups attached to amide nitrogen atoms, a crosslinking catalyst and a dihydroxy amine, and heating the coating to crosslink the polyamide. The electrophotographic imaging member may be imaged in a process involving uniformly charging the imaging member, exposing the imaging member with activating radiation in image configuration to form an electrostatic latent image, developing the latent image with toner particles to form a toner image, and transferring the toner image to a receiving member.

摘要： A corona generating assembly for charging a photoconductive surface includes a corona generator connected to a relatively large first voltage source to produce ions directed to the photoconductive surface. A conductive screen member or scorotron grid is operatively connected to a second voltage source to control the flow of ions generated from said corona generator to and through said conductive screen. The conductive screen and corona generator are arranged such that the conductive screen is between the corona generator and the photoconductive surface to be charged. A switching arrangement is provided for operatively connecting the conductive screen member with a third voltage source when the first and second voltage sources are removed from the corona generator and conductive screen. Through this arrangement an electrical potential is impressed on the conductive screen member to create a positive electrical field which inhibits effluent outgassing to the photoconductive surface, thus preventing the development of a significant copy quality defect.
