Abstract
A flexible electrophotographic imaging member comprising a substrate and at least one imaging layer comprising a first charge transport material, free of long chain alkyl ester groups or long chain alkyl carboxyl groups, and a small amount of a different second charge transporting material containing only one long chain alkyl ester group dissolved or molecularly dispersed in a film forming binder, the at least one imaging layer having been formed by drying a coating comprising a solution of the first transporting material and second charge transporting material and the film forming polymer binder in a mixture of a low volatility solvent and a high volatility solvent. A method for fabricating this imaging member is also disclosed.
