Abstract
This invention relates to a compact, lightweight pressure fusing device for permanently fixing electrostatic toner onto a copy sheet. The pressure fusing device of this invention includes a first cylindrical pressure fusing roll and a second cylindrical pressure fusing roll. The pressure fusing rolls are positioned to form a nip therebetween. The pressure fusing rolls are each relatively rotatable about their respective longitudinal axis. Either or both of the rolls may be driven. Each of the pressure fusing rolls is rotatably fixed within a substantially rigid bearing housing and is rotatable on a bearing within the bearing housing. Both the bearing and bearing housing extend substantially the entire longitudinal length of the pressure fusing roll so that pressure applied to the bearing housing is transmitted uniformly along the roll axis of each pressure fusing roll and the roll is constrained against longitudinal deflection.
