Abstract:
A process for fabricating a flexible electrophotographic imaging member comprising:providing an imaging member comprising a flexible substrate coated with a charge generating layer having an exposed surface,applying with an extrusion die coater a first coating solution comprising a charge transporting small molecule and film forming binder to the exposed surface to form a first charge transporting layer having a thickness greater than about 13 micrometers and less than about 20 micrometers in the dried state and an exposed surface, andapplying with an extrusion die coater at least a second coating solution having a composition substantially identical to the first solution to the exposed surface of the first charge transporting layer to form at least a second continuous charge transporting layer, the at least second charge transporting layer having a thickness greater than about 13 micrometers and less than about 20 micrometers in the dried state, the at least second charge transporting layer, and any subsequently applied coating solution having a composition substantially identical to the first solution,wherein a total of three charge transporting layers are formed and each layer has a thickness in the dried state of greater than about 13 micrometers and less than about 20 micrometers and the total combined thickness of all charge transporting layers in the dried state is greater than about 39 micrometers and less than about 60 micrometers.
