    摘要: A flexible electrophotographic imaging member is disclosed which comprises a flexible substrate having an electrically conductive surface, a hole blocking layer comprising an aminosilane reaction product, an adhesive layer having a thickness between about 200 angstroms and about 900 angstroms consisting essentially of at least one copolyester resin having the following formula: ##STR1## wherein the diacid is selected from the group consisting of terephthalic acid, isophthalic acid, and mixtures thereof, the diol comprises ethylene glycol, the mole ratio of diacid to diol is 1:1, n is a number between about 175 and about 350 and the T.sub.g of the copolyester resin is between about 50.degree. C. to about 80.degree. C., the aminosilane also being a reaction product of the amino group of the silane with the --COOH and --OH end groups of the copolyester resin, a charge generation layer comprising a film forming polymeric component, and a diamine hole transport layer, the hole transport layer being substantially non-absorbing in the spectral region at which the charge generation layer generates and injects photogenerated holes but being capable of supporting the injection of photogenerated holes from the charge generation layer and transporting the holes through the charge transport layer. Processes for fabricating and using the flexible electrophotographic imaging member are also disclosed.
