    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 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.

    摘要： An electrophotographic imaging member provided with a supporting substrate, a conductive layer, a charge blocking layer, an optional adhesive layer, a charge generating layer and a charge transport layer, wherein the charge generating layer contains a photogenerating pigment and a copolyester adhesive dopant blended into a film-forming polymer binder. The doping of the charge generating layer with a copolyester adhesive permits the elimination of the need of the optional adhesive layer for effective cost saving measure. If the adhesive layer is provided, the adhesion strength between the charge generating layer and the adhesive layer is significantly enhanced by up to about four times.
