Zusammenfassung:A flexible imaging member which does not require the use of an anti-curl back coating is disclosed herein. The flexible imaging member has a layer comprising two charge transport molecules dispersed in a film-forming polymer binder and an overcoat layer. The first charge transport molecule is a biphenyl amine, terphenyl diamine, or bis(triarylamine) stilbene. The second charge transport molecule is a bis(triarylamine), tri-p-tolylamine, or triphenylamine. The weight ratio of second charge transport molecule to first charge transport molecule is from about 90:10 to about 66:34. Trifluoro acetic acid is also added to the layer containing the charge transport material.
