ABSTRACT:
A wrinkle prevention structure is employed in an electrophotographic imaging device using a continuous form recording sheet. The structure is provided with a guide member disposed on the upstream side of a pair of fixing rollers. The guide member has a guide surface extending substantially horizontally for guiding the recording sheet toward a nip between the pair of fixing rollers, and a tension surface arranged on downstream side of the guide surface. The upstream side end of the tension surface is connected with the downstream side end of the guide surface, the downstream side end of the tension surface is formed substantially arc-shaped, and the tension plane is upwardly inclined with respect to the guide surface.
