Appeal No. 2004-2008
Application No. 09/955,030
BACKGROUND
Appellants’ invention relates to a photosensitive member having a
protective exterior surface layer containing tantalum doped tin oxide
having a mean particle size of 0.3 to 1.0 micrometers. According to
Appellants, the protective layer prevents damage to the photosensitive
layer and improves durability. (Brief, p. 3). Claims 13 and 34, which are
representative of the claimed invention, appear below:
13. A photosensitive member comprising:
a photosensitive layer; and
an exterior surface layer containing tantalum doped tin oxide
having the mean particle size of 0.3 to 1.0 micro-meters.
34. A photosensitive member comprising:
a substrate;
a charge generating layer being formed on the substrate and
containing an organic charge generating material;
a charge transporting layer being formed on the charge
generating layer and containing a charge transporting
material and a first binder resin; and
an exterior surface layer being formed on the charge
transporting layer and containing tantalum doped tin oxide
having the mean particle size of 0.3 to 1.0 micro-meters and a
second binder resin.
