Abstract
An exposed layer in an electrophotographic imaging member is provided with increased resistance to stress cracking and reduced coefficient of surface friction, without adverse effects on optical clarity and electrical performance. The layer contains a polydimethylsiloxane copolymer and an inactive film forming resin binder.
Claims18
An electrophotographic imaging member, comprising at least one exposed layer which contains a polydimethylsiloxane copolymer and a film forming resin binder, the polydimethylsiloxane copolymer being present in an amount to prevent undue phase separation, said layer being selected from the group consisting of a charge transport layer and an anti-curl layer.
An electrophotographic imaging member comprising:
- a substrate layer;
- a charge generating layer;
- and
- a charge transport layer which contains about 99 to about 50 parts by weight of an inactive film forming resin binder, about 1 to about 50 parts by weight of a polydimethylsiloxane copolymer, and charge transport molecules.
An electrophotographic imaging member comprising:
- a substrate having a conductive layer;
- a charge blocking layer;
- an adhesive layer;
- a charge generating layer;
- and
- a charge transport layer which contains a weight ratio of 1:0.95:0.05 of aromatic amine:polycarbonate resin:PDMS bisphenol A block copolymer.
