A compliant pressure roller (10) for creating uniform pressure at a nip
(42) has a stationary inner core (12). A plurality of shoes (14) is
pivotally mounted to the stationary inner core. Non-magnetic dividers
(16) create a plurality of annular chambers (18) and one shoe occupies
one of the chambers. A magneto-rheological fluid fills each of the
chambers and a plurality of magnetic field generators (13) changes a
magnetic field in each of the chambers. A thin, rotatable shell (24)
surrounds the plurality of chambers, shoes, and stationary inner core.
