Abstract: A heat roll type fixing arrangement for fixing a toner image on a paper includes an inlet guide plate which constitutes a lower guide plate for guiding the paper toward a nipping section of a fixing roll pair. Two ribs are provided in a central portion of a guide surface of the guide plate with respect to the widthwise direction of the guide surface. The front end of the guide plate is notched at opposite sides of the central portion such that it is sequentially inclined toward opposite side edges of the guide plate while sequentially approaching the nipping section. The guide plate is so arranged as to position the highest point of the tip of each rib which is closest to the nipping section in a predetermined spatial range.
