6, ll. 31-37). The layer 21a swells to absorb water from ink at low
temperatures, and contracts to release water at high temperatures. A cooler
28 is used to cool the surface of the transfer drum 21 so that the layer 21a
will absorb the water in the ink ejected from recording heads 23C, 23M, and
23Y (col. 6, ll. 2-17). The ink is then transferred to a recording medium S
by fixing roller 25 (col. 6, ll. 17-20). After the transfer station, a heater 27 is
used to heat layer 21a to a contraction phase to cause release of the water
from the layer 21a (col. 6, ll. 21-29).
In the eighth embodiment described by Takei, the charge on the ink
particles emitted by recording head 53 is opposite to the charge applied to
the transfer drum 51 so that the ink will remain on the transfer drum due to
the electric field effect (col. 9, ll. 41-43 and col. 10, ll. 4-6). Thereafter, the
ink on the transfer drum 51 is transferred to recording medium S (col. 10, ll.
7-10).
PRINCIPLE OF LAW
Anticipation is established when a single prior art reference discloses
expressly or under the principles of inherency each and every limitation of
the claimed invention. Atlas Powder Co. v. IRECO Inc., 190 F.3d 1342,
1347, 51 USPQ2d 1943, 1946 (Fed. Cir. 1999); In re Paulsen, 30 F.3d 1475,
1478-79, 31 USPQ2d 1671, 1673 (Fed. Cir. 1994).
ANALYSIS
We agree with Appellant that Takei heats the transfer drum “after the
image is transferred,” whereas claim 33 on appeal heats the transfer belt
prior to the transfer of the image to the print medium. We additionally agree
with Appellant that Takei does not use an electrical charge on the ink to
