Abstract
A pressure roll is disclosed particularly for fixing and developing sheet material which is treated by passing through a high pressure nip defined by a pair of the rolls. The roll includes a support shaft and a cylindrical roll body secured to the shaft. To produce a uniform force along the pressure nip when a pair of the rolls are placed under load, the body is formed from a body material having a modulus of elasticity which varies as a function of position along the length of said body. The body is encased in a cylindrical shell.
