    摘要: A seamed flexible imaging member and a method of constructing a flexible imaging sheet is disclosed. The method of constructing a flexible imaging sheet comprises the steps of overlapping and forming. In the step of overlapping, a first marginal end region and a second marginal end region of the sheet are overlapped. In the forming step, a substantially planar surface is formed, extending in a direction transverse to the sheet with one end of the planar surface being integral with the sheet adjacent one end of the sheet and the other end of the planar surface being integral with the sheet adjacent the other end of the sheet, for securing the first marginal end region and the second marginal end region to one another by a seam. The seamed flexible imaging member comprises a sheet having a first marginal end region and a second marginal end region. The first marginal end region and the second marginal end region of the sheet are secured to one another by a material which may include a portion of the sheet, a separate securing material or both. The material defines a planar surface extending in a direction transverse to the sheet with one end of the planar surface being integral with the sheet adjacent one end of the sheet and the other end of the planar surface being integral with the sheet adjacent the other end of the sheet. The planar surface minimizes stress on the sheet, particularly stress caused by the flexible imaging member bending over small diameter rollers of a belt module within an electrophotographic imaging apparatus.

    摘要: An electrophotographic imaging member having a charge generating layer and a charge transport layer overlayed thereon is provided. The charge transport layer has a lower surface and an upper surface, wherein the lower surface is in contiguous contact with the charge generating layer. The charge transport layer comprises a film forming polymer binder and a charge transport compound molecularly dispersed or dissolved therein to form a solid solution. The concentration of the charge transport compound in the charge transport layer decreases from the lower surface to the upper surface. In such a construction, the resulting charge transport layer exhibits enhanced cracking suppression, improved wear resistance, excellent imaging member electrical performance, and improved copy print out quality.

    摘要: A system for increasing the life of flexible photoreceptor belt in a copier/printer includes tensioning and de-tensioning the photoreceptor belt. The photoreceptor belt is de-tensioned at the end of daily use, on weekends, and on non working days in order to reduce belt dimensional elongation due to creep which thereby suppresses the development of charge transport layer cracking in the photoreceptor belt and increases belt service life of the photoreceptor by a factor of about 2.times..

    摘要: Disclosed herein is a flexible imaging member having a high concentration of a charge transport compound having optimum enhanced mechanical and electrical characteristics. By increasing the concentration of the charge transport compound to a level of from about 55 weight percent or more, including from about 55 weight percent to about 70 weight percent, and from about 55 weight percent to about 65 weight percent, a flexible imaging member can be produced with reduced residual voltage and/or improved sensitivity. Furthermore, the fatigue cracking resistance of the charge transport layer can be improved through the implementation of a heat stress release process described more particularly herein.
