Abstract

PURPOSE:To ensure an even application of pressure with a roller of a small diameter, by forming at least one of the two pressure fixing rollers into a cheese shape with a rocking motion given to at least one shaft of these rollers to the other shaft and thus shifting the pressure application point toward the width of the paper. CONSTITUTION:An end of the shaft of a cheese-shaped pressure roller 4 is shifted upward by a spring 56, and the other end is connected to a rocking lever 6 via a bearing that can give an eccentricity to the shaft. When a motor is turned, an eccentric cam is turned. Thus the lever 6 rocks the shaft of the roller 4. In this case, the positional relation between the rollers 1 and 4 varies as shown by the solid lines and dotted lines in the figure. According to this change, the pressure application point shifts over the full width of the paper 3. The pressure application point has actually a certain area, and accordingly an even pressure can be substantially applied to the entire surface of the paper 3 by increasing greatly the rocking speed of the roller 4 campared with the feeding speed of the paper 3.
