ABSTRACT:
A roller for use in an imaging system includes a variable hardness, fluid-pressurizable roller core, and a roller cover surrounding the roller core. A source of pressurized fluid can be used to pressurize the roller core to a fixed, predetermined pressure prior to installation of the roller core in an imaging system. Alternatively, a variable-pressure source of pressurized air can be used to variably pressurize the roller core during operation of the imaging system.
