ABSTRACT:
Image forming apparatus includes a fuser which has a fusing sheet for contacting the image bearing surface of a receiving sheet. The fusing sheet is attached at one end to a fusing sheet drum and at the other end to a spring for urging the fusing sheet in a first direction. The fusing sheet drum is rotatable in a first direction to allow the spring to move the fusing sheet in the first direction, which moves both the fusing sheet and the receiving sheet through a pressure nip formed by the fusing sheet drum and a pressure roller. The fusing sheet drum is rotatable in the second direction opposite the first direction for rewinding the fusing sheet on the fusing sheet drum. During the rewinding motion of the fusing sheet, the receiving sheet is separated from the fusing sheet by forcing the fusing sheet around a sharp bend.
