Abstract
Abstract An imaging member in accordance with claim 1 wherein the oxygenated polysilylene is of the formula ##STR1## wherein R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , R 7 and R 8 are independently selected from the group consisting of alkyl, aryl, substituted alkyl, and substituted aryl, and alkoxy; m is from 0 to 0.98 mole percent; n is from 0 to 0.98 mole percent; p is from 0 to 0.98 mole percent; q is from 0.02 to 0.12 mole percent subject to the provisions that the sum of m+n+p is less than or equal to 0.98; and the sum of m+n+p+q is equal to 1.
