Claim Text:
1. A flexible imaging member comprising: a flexible substrate; a charge generating layer disposed on a first side of the substrate; and at least one charge transport layer disposed on the charge generating layer, wherein the charge transport layer comprises a charge transport compound dispersed in a binary polymer blend binder, the binary polymer blend binder comprising a low surface energy copolymer being a low surface energy random copolymer or a low surface energy graft copolymer and an organic acid containing A-B diblock copolymer having a general formula of wherein the block A polycarbonate repeating unit in the A-B diblock copolymer is a bisphenol polycarbonate selected from the group consisting of wherein z is an integer representing the numbers of repeating segmental carbonate unit, and is from about 9 to about 18, from about 27 to about 36, or from about 45 to about 54 and further wherein the block B organic acid containing repeating unit in the A-B diblock copolymer is selected from the group consisting of: wherein W is a moiety selected from the group consisting of an aromatic, aliphatic, aryl, phenyl, and alkylene, and y is from about 1 to about 6; wherein W is a moiety selected from the group consisting of an aromatic, aliphatic, aryl, phenyl, and alkylene, and y is from about 1 to about 6; wherein W is a moiety selected from the group consisting of an aromatic, aliphatic, aryl, phenyl, and alkylene, and y is from about 1 to about 6; wherein W is a moiety selected from the group consisting of an aromatic, aliphatic, aryl, phenyl, and alkylene, and y is from about 1 to about 6; wherein W is a moiety selected from the group consisting of an aromatic, aliphatic, aryl, phenyl, and alkylene, and y is from about 1 to about 6; wherein W is a moiety selected from the group consisting of an aromatic, aliphatic, aryl, phenyl, and alkylene, and y is from about 1 to about 6; wherein y is from about 1 to about 6; wherein y is from about 1 to about 6; wherein y is from about 1 to about 6; wherein y is from about 1 to about 6; wherein y is from about 1 to about 6; wherein y is from about 1 to about 6; and wherein p is from 3 to 8 or from 4 to 6; and y is from about 1 to about 6.
