Abstract
A fusing station (25) of an electrographic apparatus fixes in a single pass a duplex resinous powder color image (8, 18) to a support material in sheet-form (9) as the sheet is moved over a predetermined path (7). The station comprises two heated fixing rollers (1, 11), rotating in contact with each other, driving means to rotate the fixing rollers, pressing means for applying a meshing force between the fixing rollers, heating sources (4, 14) which have substantially identical characteristics. Both fixing rollers comprise a heat conducting core (3, 13) and a resilient covering (2, 12) which by the pressure between both rollers forms a heating nip. A symmetrical fixing operation on both sides of the sheet is provided. Hereto, the fixing rollers have a substantially identical construction, are positioned symmetrically to the path of the sheet and rotate synchronously to the advancement of the sheet.
