This invention discloses an apparatus for holding and transporting a hollow flexible belt throughout a coating process. The apparatus includes a spring and shaft assembly which is placed into the hollow portion of a seamless flexible belt. The spring portion of the assembly until it is transformed into a belt carrying chucking device. The chucking device is then attached to a mechanical handling device, and the the belt is transported through the dipping and coating process. This allows the belt to be transformed into an organic photoreceptor. The chucking device and flexible belt are then removed from the mechanical handling device, and the chuck is removed from the inside of the photoreceptor.
摘要:
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.

An electrophotographic imaging member including a supporting substrate, an electrically conductive layer including at least a partially crosslinked polymer having a backbone derived from an alkyl acrylamidoglycolate alkyl ether, a charge blocking layer including a polymer having a backbone also derived from an alkyl acrylamidoglycolate alkyl ether and at least one photoconductive layer. Preferably, the backbone derived from an alkyl acrylamidoglycolate alkyl ether is a copolymer of methyl acrylamidoglycolate methyl ether and a vinyl hydroxy ester or vinyl hydroxy amide. This imaging member may be prepared by a coating process and employed in an electrostatographic imaging process.
摘要:
A method for removing a residue, such as lateral charge migration (LCM) film, from an imaging member includes contacting at least a portion of the imaging member with a wash liquid capable of removing the residue. The wash liquid containing the residue is then removed, for example, by applying an absorbent material such as a toner, to the contacted portion of the imaging member.

A process for forming an imaging member, includes providing an imaging member substrate, and applying at least a charge generating layer and a charge transport layer to the substrate, where at least one of the charge generating layer and the charge transport layer is applied from a coating solution in a dip coating process wherein a residence time of the substrate in the coating solution is greater than 1 second. The photoreceptor exhibits increased adhesion between the charge generating layer and the charge transport layer, as well as between other layers.
