Abstract
An image forming apparatus includes a photosensitive drum, scuff rollers to move a continuous recording paper along a transfer path, a tractor disposed upstream from the scuff rollers, back tension rollers disposed upstream from the tractor to exert a tension on the recording paper, a speed controller to adjust the transfer speed of the recording paper, and a pressure controller to adjust the pressure acting on the recording paper. The speed controller adjusts the circumferential speed of the back-tension rollers and/or scuff rollers and the pressure controller adjusts the pressure of the back-tension rollers and/or scuff rollers in order to reduce positional deviation of the recording paper.
