Abstract
An image forming apparatus includes a feed roller mechanism disposed downstream of a transfer corotron 412 constituting a transfer section and composed of driven rollers 506 located on both edges of a continuous recording medium 100 which are outside an image transfer area and a drive roller 508 extending over the whole width of the continuous recording medium 100, so that when transferring a toner image from an image recording member 402, on which the toner image is to be formed, to the continuous recording medium 100, friction by the rollers achieves reliable conveyance against an attraction between the image recording member 402 and the continuous recording medium 100 without disturbing an unfixed image on the continuous recording medium 100. The image forming apparatus further includes a line sensor 43 for detecting a position where a reference edge of the recording medium is present, a line sensor output device which judges a position of the recording medium reference edge in cooperation with the line sensor to send a recording medium reference edge position signal or mask 61 adjustable in position for shielding a portion of a detection window of the line sensor, a recording m…
