Abstract
A plurality of helical groove sections are provided on outer peripheral surfaces of press rollers provided in a curl elimination mechanism. Each of the groove sections assumes a shape extending in the circumferential direction of the respective press rollers; that is, a direction oblique to a transport direction of paper. Hence, when compared with a case where the groove sections are aligned in the transport direction of the paper, the paper is less susceptible to traces of the groove sections. Since the groove sections are provided on the press rollers, an attempt can be made to enhance dimensional accuracy of or reduce the weight of the press rollers.
