PRESSURE ROLLERS FOR TONER FUSING STATION

摘要

A pressure roller and apparatus for pressure fixing imaging powder to a substrate in an electrostatic duplicating machine, the apparatus including a pair of fixing rollers in pressure contact along a narrow band The fixing rollers are hollow cylindrical rollers with parallel longitudinal axes and are rotatably supported by pressure transfer rollers inside each fixing roller. The pressure transfer rollers in each fixing roller are rotatably supported by a shaft and housing. Pressure supplied by loading means at the ends of the shafts is distributed uniformly along the pressure transfer rollers without causing bending of the fixing rollers which formerly required that the rollers be skewed or supported by an auxiliary roller.
