Abstract
There is described a method for forming an electrophotographic imaging member wherein a selenium compound dispersed in an electrically insulating polymer matrix is photochemically or thermally decomposed and elemental selenium and a charge carrier transport compound are deposited within the binder matrix.
Claims2
A method for preparing an electrophotographic imaging member comprising the steps of:
- a. providing a layer of a solid phase dispersion on a conductive substrate, said dispersion comprising an organoselenium compound which is represented by the structural formula ##STR2## wherein R has from 1 to about 20 carbon atoms and may be alkyl, aryl substituted alkyl, amino derivatives of alkyl and aryl substituted alkyl;
- aryl, alkyl substituted aryl, amino substituted aryl, alkylamino substituted aryl, arylamino substituted aryl, alkylcarbonyl, arylcarbonyl, and aminosubstituted derivatives of alkylcarbonyl and arylcarbonyl;
- and
- X and Y are independently selected from the group consisting of H and alkyl and perfluoroalkyl having from 1 to about 4 carbon atoms in an electrically insulating polymeric binder matrix;
- and
- b. subjecting said layer to sufficient thermal energy or electromagnetic radiation to which said organoselenium compound is responsive to decompose at least a substantial amount of said organoselenium compound whereby elemental selenium and a carbazole derivative are deposited within said layer.
