Abstract

PURPOSE: To prevent offset phenomenon and obtain good quality images by crossing a top roll and a bottom roll by having a certain angle.
CONSTITUTION: A top roll 1 is turnably fixed to a housing 4 by way of bearings and a bottom roll 2 is supported by the guide blocks 11 of the housing 4 by way of bearings and is movable in the vertical directions within the housing 4. The abovementioned bottom roll 2 is provided by being crossed to the top roll 1 at a minute angle α within a range of 1.36° >α>40'. In addition, a backup roll 3 is supported by guide blocks 12 by way of bearings and is movable in the vertical directions. A leaf spring 13 is provided to the lower part of the guide blocks 12 and its pressing force is adjusted to desired pressures by a pressure bolt 15. By crossing the rolls at the abovementioned minute angle, the abovementioned pressure is also acted upon the horizontal direction to be applied in the vertical direction and the horizontal pressure becomes the pressure to rub the copying paper, thus the offset phenomenon of the toner may be prevented at the time of pressure-fixing the toner image.
