Squeak and deletion resistant imaging member and system

An imaging member includes a charge generation layer and a contiguous charge transport layer containing a diamine and a compound within the scope of formula (II):wherein each R1 and R2 is independently one of an alkyl having 1 to 8 carbon atoms, aryl, alkaryl and aralkyl, where the aryl is a phenyl group or a condensed ring group, and where the alkyl group of the alkaryl and aralkyl has 1 to 4 carbon atoms, R3 and R4 are independently hydrogen or CH3, and R5 is one of an alkyl having 1 to 8 carbon atoms, aryl, alkaryl and aralkyl as defined above, or a disubstituted aminophenyl group wherein each substituent is independently one of an alkyl having 1 to 8 carbon atoms, aryl, alkaryl and aralkyl as defined above. A electrophotographic system includes a cleaning blade and the above imaging member drum.
