Abstract: An imaging member includes a charge generating layer and a charge transport layer. The charge transport layer includes a first surface in contact with the charge generating layer and a second surface. The charge transport layer includes a film forming polymer binder and a charge transport component dispersed therein. The concentration of the charge transport component in the charge transport layer is at a peak in a region of the charge transport intermediate the first and second surfaces of the charge transport layer.

Abstract: An imaging member comprising a barrier or under-layer intermediate a photogenerating layer and charge transport layer to reduce charge deficiency spots. The barrier under-layer comprises a film forming polymer binder selected from a conductive polymer binder, a non-conductive polymer binder, or mixtures thereof. Optionally, the barrier layer can include a small amount of a charge transport material.

Abstract: The amount of lateral charge migration (LCM) on a photoreceptor is quantified by measuring the average potential of a latent image formed on the photoreceptor surface. The surface is first uniformly charged, then exposed a first time to an image. After a waiting period during which LCM may occur, the surface is exposed a second time to the image. After another waiting period, the average potential is measured. The amount of LCM may be quantified by varying the waiting periods.

Abstract: A belt loading apparatus has been provided for loading a flimsy continuous belt onto a belt support and drive assembly including a vertical front end having a first shape and without damage to the belt. The belt loading apparatus includes a wall member defining a sleeve including an outer surface having a total outer surface area, a first edge and a second and opposite edge. The second edge has a vertical profile having a second shape such that the second shape of the second edge is a mirror image of the first shape of the belt support and drive assembly. The belt loading apparatus then includes friction reducing members formed on the outer surface of the sleeve for temporarily supporting and spacing a flimsy continuous belt to be loaded onto the belt support and drive assembly. The friction reducing members each have a belt contact area such that a sum total of belt contact areas of all the friction reducing members is significantly less than the total outer surface area of the sleeve.
