摘要： This invention discloses a method of holding and transporting a hollow flexible belt throughout a coating process. The method includes placing an expandable insert into the hollow portion of a seamless flexible belt, and expanding the insert until it forms a chucking device with a protrusion on at least one end. A mechanical handling device is then attached to the protrusion, and will be used to move the chuck and the belt through the dipping process, as materials needed to produce a photosensitive device are deposited onto the surface of the belt, allowing it to be transformed into an organic photoreceptor. The chucking device and flexible belt are then removed from the mechanical handling device, the belt is cut to the desired width, and the chuck is removed from the inside of the photoreceptor.

摘要： A method for forming an electrostatographic photoreceptor includes the steps of selecting a desired sensitivity range and a desired light intensity for a photoreceptor and forming the photoreceptor having the desired sensitivity range and desired light intensity. The photoreceptor includes a supporting substrate and a photogenerating layer including a charge generating material, formed by coating the photogenerating layer on the supporting substrate. The charge generating material is formed by a process including dispersion milling a photogenerating material for a selected period of time, selected in accordance with the desired sensitivity range and the desired light intensity, to adjust the desired sensitivity range and desired light intensity of the photoreceptor.
