Abstract
A process for fabricating an electrophotographic imaging member including forming a charge generating layer, forming an undried charge transport layer coating by applying to the charge generating layer a solution selected from either or both the group consisting of PA1 a solution including a charge transport molecule, a first film forming binder and at least a first solvent and PA1 a solution including a charge transporting polymer and at least a first solvent, forming an undried overcoat layer coating by applying to the undried charge transport layer coating an overcoat layer coating solution including a second film forming polymer and at least a second solvent, the charge transport molecule and first film forming polymer or either or both a charge transporting polymer being substantially insoluble in the second solvent and the second polymer being substantially insoluble in the first solvent, applying heat to both the undried charge transport layer coating and the undried overcoat layer coating to migrate the first solvent from the charge transport layer coating through the undried overcoat layer coating while maintaining the overcoat layer coating porous to migration of the firs…
