Upper Fixing Roller; Removing The Fixing Roller - Canon iR6570 series Service Manual

As the pressure roller is used more and more, its rubber surface can start
to discolor. The change, however, will not affect its performance or
output images. Further, the physical properties of the roller can permit
its surface to start to wrinkle. The roller, however, is free of wrinkles
when it is heated and its performance will not be affected, thus not
requiring replacement.
