Claims
- 1. A method of forming an imaging member comprising a photoconductive layer having plural photoconductive paths oriented substantially perpendicular to a surface of said layer and a conductive substrate, said method consisting essentially of:
- a. preparing a photoconductive block copolymer by anionic copolymerization of a polynuclear condensd aromatic vinyl compound selected from the group consisting of 3-vinylpyrene, 2-vinylanthracene, 2-propenyl-2-anthracene and 2 vinyl-N-alkyl carbazoles with a monomer selected from the group consisting of 1,3-butadiene, 1,3-pentadiene (piperyline), 2-methyl-1,3-butadiene (isoprene) 2,3-dimethyl-1,3-butadiene and cyclic octamethyl tetrasiloxane;
- b. extruding and cooling a melt of said copolymer to form an extrusion having lamellae of at least two phases, one phase being photoconductive and the other phase being elastomeric, said lamellae being disposed in a direction lying substantially parallel to the direction of extrusion, and cutting said extrusion transerversely to form said layer; and
- c. placing said layer upon a conductive substrate, with said lamellae being disposed in a direction substantially normal to the horizontal plane of said substrate to form an imaging member.
