Appeal No. 94-3960
Application 07/997,489
Thomas E. Orlowski et al. (Appellants) appeal from the
examiner's final rejection of claims 1 through 24, which are
all the claims remaining in the application.
Claim 1 is representative of the subject matter on appeal
and reads as follows:
1. A process for preparing a donor roll having an
electrode pattern comprising:
(a) providing a cylindrically shaped insulating
member;
(b) coating the insulating member with a photo or
thermally sensitive composition comprised of a polymeric
material and a conductive metal nucleating agent;
(c) patterning the composition, resulting in a first
composition portion corresponding to the electrode pattern and
a second composition portion; and
(d) depositing conductive metal on the first
composition portion, resulting in the electrode pattern which
is capable of being electrically biased to enable detachment
of toner particles from the donor roll.
According to the specification, the term "a donor roll" is
defined as a device for "transporting charged toner to the
development zone." See specification, page 1. The donor roll
must not only be capable of attracting toner from a magnetic
roll, but also be capable of being electrically biased to
enable detachment of toner to cause formation of a toner
