A coating method using an endless, hollow substrate in the shape of a belt or cylinder having an outer surface, an inner surface, a first end, and an open second end, including: (a) depositing via dip coating a first coating solution over the outer surface of the substrate and simultaneously over the inner surface by permitting the first coating solution to flow through the second end to be deposited on the inner surface, thereby depositing a first layer over the outer surface and the inner surface; and (b) depositing via dip coating a second coating solution over the first layer on the outer surface of the substrate and simultaneously over the first layer on the inner surface by permitting the second coating solution to flow through the second end to be deposited on the first layer on the inner surface, thereby depositing a second layer over the outer surface and the inner surface, wherein the first layer and the second layer are deposited over all of the outer surface and the inner surface of a predetermined section of the substrate, wherein the first coating solution and the second coating solution are selected from the group consisting of a charge generating solution, a charge transport solution, an adhesive layer solution, and a charge blocking layer.

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.
