摘要： A coating process for the fabrication of organic photoreceptors employs an electrically conductive single slot die biased to allow an electric field between the die and the ground plane on the photoreceptor substrate. The homogenous coating dispersion is fed through the die at a predetermined gap and rate to control coating thickness at the same time that an electric field is applied. The formulation, rheology, particle mobility, coating speed, electric field and the like are controlled so that the photogenerator particles migrate to the substrate in the dwell time defined by the coating die region.

摘要： A method of forming one or more polymer containing layers on a substrate using ink jet nozzles. The method is particularly suited to forming one or more polymer containing layers of a photoreceptor. The polymer containing layers may be formed by moving a substrate, in particular a cylindrical substrate, past the ink jet nozzles, by moving the ink jet nozzles over the substrate, or both. The ink jet nozzles are capable of being independently controlled in order to permit precise location of the coating on the substrate.

摘要： A dryer with zone temperature controls for drying thick polymer-solvent layers on a substrate. The dryer is formed with several heating elements located in an air duct. The cool air is heated a specific amount as it passes each heating element. The heated air is then applied to the polymer-solvent solution on the substrate in a continuous fashion so that the polymer-solvent solution slowly heats up as it passes through the drying apparatus. The preferred design is to ensure a zone residence time of less than 10 seconds and a web heating rate of 10.degree. F./second or less. Most preferred design is a zone residence time less than 5 seconds and a heating rate less that 5.degree. F./second. The dryer is designed to have a continuous temperature gradient, especially in the critical later stages of drying when the solvent content of the film is less than 20%.
