Claims

[Claims for Utility Model Registration] 1. A pressure developing device comprising a pair of pressure rolls, each of which is supported by a back-up roll, wherein one of the pressure rolls and a bearing that holds the back-up roll. A pressure developing device, characterized in that it is directly attached to a frame and configured to be able to move toward and away from the other pressure roller. 2. In the apparatus according to claim 1, bearings for supporting both ends of each pressure roll are fitted directly to both side walls of a housing that faces each other at a constant interval and functions as a strength member of the pressure developing device. The two pressure rolls are disposed so as to be movable only in directions that allow them to approach and separate, and the upper pressure roll is biased downward by a spring with a back-up roll interposed, and the lower pressure roll is biased downward by a spring. A pressure developing device characterized in that the pressure roll can come into contact with and separate from the upper pressure roll together with the frame by interposing a back-up roll.
