Patent ID: 7297458

Claim:
A photoconductive member comprising a supporting substrate, a hole blocking layer having a thickness of from about 1 to about 20 microns, a photogenerating layer, and a charge transport layer; wherein the photogenerating layer comprises a photogenerating component and an electron transport component, and wherein the electron transport component is selected from the group consisting of a carbonylfluorenone malononitrile of the formula wherein each R is independently selected from the group consisting of hydrogen, alkyl, alkoxy, aryl, and halide; a nitrated fluorenone of the formula wherein each R is independently selected from the group consisting of alkyl, alkoxy, aryl, and halide, and wherein at least two R groups are nitro; a diimide selected from the group consisting of N,N′-bis(dialkyl)-1,4,5,8-naphthalenetetracarboxylic diimide and N,N′-bis(diaryl)-1,4,5,8-naphthalenetetracarboxylic diimide represented by the formula wherein R 1 is alkyl, alkoxy, cycloalkyl, halide, or aryl; R 2 is alkyl, alkoxy, cycloalkyl, or aryl; R 3 to R 6 are as illustrated herein with respect to R 1 and R 2 ; a 1,1′-dioxo-2-(aryl)-6-phenyl-4-(dicyanomethylidene)thiopyran of the formula wherein each R is independently selected from the group consisting of hydrogen, alkyl, alkoxy, aryl, and halide; a carboxybenzylnaphthaquinone of the alternative formulas wherein each R is independently selected from the group consisting of hydrogen, alkyl, alkoxy, aryl, and halide; and a diphenoquinone of the formula wherein each R is independently selected from the group consisting of hydrogen, alkyl, alkoxy, aryl, and halide.
