heater layer (110)." Id. at ll. 23-27. "Both end portions of
the outer circumference of each conductive layer (150) or
(152) are exposed to outside and there are provided a pair of
power supply sections (156) having sliding terminals (154)
kept
respectively in sliding contact with the conductive layers
(150), (152). Accordingly, when current is passed through the
layer (110) from the power supply sections (156), the
resistance heater layer (110) generates heat from their
respective whole body." Id. at ll. 27-35. The examiner
admits that Nakajima fails to teach "the use of a pattern
electrode layer for one of the conductive layers ...."
(Examiner's Answer at 3.)
Observing that Satomura shows "form[ing] a line-shaped
pattern electrode on the heat resistance layer 4 of [a] fixing
roller" (id. at 7), the examiner proposes replacing either
conductive layer 150 or 152 of Nakajima with such a line-
shaped pattern electrode. (Id. at 8.) Such a replacement,
however, would have rendered Nakajima's heating region
