ABSTRACT:
An imaging member comprising a charge generation layer comprising a layer of photoconductive material and a contiguous charge transport layer of a charge transport material dissolved in a polymer of the following structure: ##STR1## wherein R', R", R'" and R"" are independently selected from the group consisting of alkyl and alkylene groups having from 1 to 12 carbon atoms, there being no more than 1 alkylene group present, x is from 4 to 5, y is from 0 to 1, n is a whole number and said polymer has a molecular weight ranging from about 1500 to about 120,000, said transport layer being substantially nonabsorbing in the spectral region at which the photoconductive layer generates and injects photogenerated holes, but is capable of supporting the injection of photogenerated holes from said photoconductive layer and transporting said holes through said charge transport layer.
