Abstract
Disclosed is a migration imaging member which comprises (a) a substrate, (b) a conductive layer comprising indium tin oxide dispersed in a polymeric binder, (c) a siloxane film charge blocking layer comprising a hydrolysis reaction product of a silane of the formula ##STR1## wherein R.sub.1 is an alkylidene group, R.sub.2 and R.sub.3 are each, independent of the other, a hydrogen atom, an alkyl group, a phenyl group, or a poly(ethyleneamino) group, and R.sub.4, R.sub.5, and R.sub.6 are each, independent of the others, alkyl groups, said siloxane having reactive hydroxyl and ammonium groups attached to silicon atoms, and (d) a softenable layer comprising a softenable material and a photosensitive migration marking material. Optionally an antistatic layer comprising indium tin oxide dispersed in a polymeric binder is situated on the surface of the substrate spaced from the softenable layer.
