    摘要： Processes and apparatus for fabricating an electrophotographic imaging member in which a web coated with a charge generation layer is coated with a charge transport layer comprising a dopant, the improvement comprising detecting the change in dopant concentration required, determining the amount of highly doped charge transport composition and amount of undoped or lowly doped charge transport composition required to achieve the change in dopant concentration, feeding the determined amounts of highly doped charge transport composition and undoped or lowly doped charge transport composition into a mixing zone, rapidly mixing the amounts of highly doped charge transport composition and undoped or lowly doped charge transport composition to form a uniformly doped charge transport composition, and applying the uniformly doped charge transport composition to the charge generation layer.

    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%.
