Abstract:
An imaging member comprising a charge generation layer and a contiguous charge transport layer, said charge transport layer comprising:(1) a diamine compound of formula (I): ##STR5##wherein R is ##STR6##and wherein X is independently selected from the group consisting of alkyl having from 1 to about 4 carbon atoms and chlorine in the ortho, meta or para position; and(2) a compound of formula (II): ##STR7##wherein R.sub.1 and R.sub.2 are independently selected from the group consisting of alkyl having 1 to 8 carbon atoms, aryl, alkaryl and aralkyl, where said aryl is a phenyl group or a condensed ring group, and where the alkyl group of said alkaryl and aralkyl has 1 to 4 carbon atoms;R.sub.3 and R.sub.4 are independently selected from the group consisting of hydrogen and CH.sub.3 ; andR.sub.5 is selected from the group consisting of alkyl having 1 to 8 carbon atoms, aryl, alkaryl, aralkyl, and disubstituted aminophenyl group having substituents independently selected from the group consisting of alkyl having 1 to 8 carbon atoms, aryl, alkaryl and aralkyl, where each said aryl is a phenyl group or a condensed ring group, and each said alkyl group of each said alkaryl and aralkyl has 1 to 4 carbon atoms;said transport layer being free of halogen containing organic solvent.
