Appeal No. 1998-2169
Application No. 08/610,069
equation (I) of from 0.01 to 0.10, and said charge-
generating layer having a multilayer structure
comprising a charge-generating layer having n-type
semiconductor characteristics and a
charge-generating layer having p-type semiconductor
characteristics:
(Sa/Sm)-1 (I)
wherein Sa is the actual surface area of the external
surface of said cylindrical electrically conductive
support and Sm, is the theoretical surface area
thereof calculated on the assumption that said
support is an ideal cylinder.
The examiner relies upon the following references as
evidence of obviousness:

Appellant’s claimed invention is directed to an organic
photoconductor comprising a cylindrical electrically
conductive support which has an external surface having an
index of surface area in the range of 0.01 to 0.10. The index
of surface area is defined in the specification and claim 1.
According to appellant, “the index of surface area of the
present invention does not require expensive processing
