ABSTRACT This invention is directed to an improved photoresponsive device comprised in the order stated of (1) an optional supporting substrate, (2) a conductive layer, (3) a photogenerating layer comprised of an inorganic photoconductive composition, or an organic photoconductive composition, dispersed in a resinous binder material comprised of a poly(hydroxyether) material selected from the group consisting of those of the following formulas: I. Image and 2-- II. Image wherein X and Y are independently selected from the group consisting of aliphatic groups and aromatic groups, Z is hydrogen, an aliphatic group or an aromatic group, and n is a number of from about 50 to about 200, and (4) in contact with the photogenerating layer a charge transport layer comprised of an electrically active composition dispersed in an insulating organic resinous binder, which composition is of the following formula: Image wherein X is selected from the group consisting of ortho (CH3), meta 3-- (CH3), para (CH3), ortho (Cl), meta (Cl) and para (Cl); as well as the use of such devices in electrostatographic imaging systems, particularly xerographic imaging systems.
