Patent ID: 7291430

Claim:
A member comprising: a substrate, wherein an electrically conductive support is included when the substrate is non-conductive; a charge blocking layer; a charge generating layer comprising a binder and a charge generating layer material selected from the group consisting of hydroxygallium phthalocyanine Type V, x- polymorph metal free phthalocyanine, and chlorogallium phthalocyanine; a charge transport layer comprising a first electron transport molecule and a binder; wherein the charge generating layer material is dispersed in a matrix comprising a second electron transport molecule and a charge transport molecule, and wherein said charge transport molecule is an arylamine; and wherein the charge generating layer comprises from 10 percent to 30 percent by weight of the binder based on the total weight of the charge generating layer after drying, the charge generating layer comprises from about 35 percent to about 65 percent by weight of the charge transport molecule and the electron transport molecule based on the total weight of the charge generating layer after drying, and the charge generating layer comprises from about 1 percent to about 40 percent by weight of said second electron transport molecule based on the combined weight of the charge transport molecule and the electron transport molecule in the charge generating layer after drying, and wherein said second electron transport molecule is a nitrated fluorenone derivative represented by: wherein each R is independently selected from the group consisting of hydrogen, alkyl containing from about 1 to about 40 carbon atoms, alkoxy containing from about 1 to about 40 carbon atoms, phenyl, substituted phenyl, naphthalene and anthracene, alkylphenyl containing from about 6 to about 40 carbons, alkoxyphenyl containing from about 6 to about 40 carbons, aryl containing from about 6 to about 30 carbons, substituted aryl containing from about 6 to about 30 carbons, halogen, and nitro, and wherein at least 2 R groups are chosen to be nitro groups.
