layer 6 on the base covering 4 connected to the cylinder body,
which is grounded, in an effort to carry away the electro-
static charge build up on the cylinder surface. The Examiner
directs us to the drawing figure and col. 2, line 10, through
col. 3, line 26, of the Köbler reference. The Examiner argues
that it would have been obvious to one of ordinary skill in
the art at the time the invention was made to provide the base
covering 62 of DeMoore with an electrically conductive layer
connected to the cylinder body as taught by Köbler so as to
alleviate the electrostatic charge build up problem on the
cylinder surface.
Appellants argue on pages 5 through 7 of the brief,
that there is no suggestion or motivation to substitute
Köbler's aluminum conductive layer 6 in the place of DeMoore's
non-conductive base covering 62. Appellants argue that
Appellants' claims require that the underlying low friction,
conductive transfer member makes direct electrical contact
with the underlying conductive sheet support surface of the
transfer cylinder. Appellants point out on page 7 of the
brief that Köbler discloses that the felt underlay packing 4
