摘要： A fixing roller used in an electrophotographic device includes a coupling with a drive key that engages an end of a pressing roll that contains a key groove. Disposed between the coupling and the end of the pressing roll is a spacing member. This spacing member decreases the rate at which the key groove and the drive key deteriorate when two fixing rollers are used as pair to fix toner on a printed page. The spacing member is made of plastic, a sintered metal alloy, or other material. Also, the spacing member is lubricated to further prevent friction and the key groove of the pressing roll is lined with an abrasion resistant material to further prevent deterioration of the drive key and the key groove.
