Abstract
A roller for contacting print media in an image forming device includes a tubular core formed of a first material and having an inner surface and an outer surface, and a sleeve formed of a second material and surrounding a portion of the tubular core. The sleeve includes an inner portion surrounding a portion of the inner surface of the tubular core and an outer portion surrounding a portion of the outer surface of the tubular core. The outer portion of the sleeve has an outer surface for contacting the print media. As such, contact of the print media with the roller is made by the outer portion of the sleeve when the print media is routed through the image forming device.
