Abstract
An improved heating roller type fusing unit for a copy machine is disclosed in which a guide plate and a guide roller are added to the existing fusing unit consisting of a heating roller and a pressing roller. The guide plate performs the function of conveying the paper to the nip portion, while the guide roller performs the function of applying a lateral tension on the paper before the paper enters into the nip portion, with the result that the nip portion has only to carry out the fusing function.
