A copy sheet distortion-removing fusing apparatus is provided for preventing fused image deletions and poor fused copy sheet appearance. The copy sheet distortion-removing fusing apparatus includes a frame; a first pair of rotatable rollers mounted to the frame and forming a first nip for receiving and moving a copy sheet therethrough. The first pair of rotatable rollers includes a heated fuser roller, and a pressure roller forming the first nip against the fuser roller. The copy sheet distortion-removing fusing apparatus also includes a second pair of rotatable rollers forming a second nip for immediately receiving and moving therethrough a fused copy sheet coming from the first nip. Each roller of the second pair of rotatable rollers includes a hard surface layer. Rollers of the second pair of rollers are mounted in pressure engagement against each other within the second nip for flattening out any distortions in the fused copy sheet being moved therethrough, thereby preventing poor fused copy sheet appearance on such fused copy sheet.
