Abstract
PURPOSE:To prevent a roller from being stained by covering the outer peripheral surface of a base rubber layer, and providing a nonadhesive layer of multi-layered constitution which is porous and oil-permeable and has the hole diameter of a lower layer part larger than the hole diameter of an upper layer part. CONSTITUTION:The noncohesive elastic body roller 1 for fixation is formed by incorporating oil for offset prevention such as silicon oil in the base rubber layer 2 and forming the nonadhesive layer 5 of multi-layered structure which is porous and oil- permeable and has the hole diameter of the blow hole of the lower layer 3 larger than the hole diameter of the upper layer part 4 on the outer peripheral surface of the roller. When paper to be fixed passes the roller 1, oil such as silicone oil incorporated in the base rubber layer 2 passes through the large-diameter bow hole formed in the lower layer part of the nonadhesive layer as the roller is driven. The hole diameter of the blow hole is larger than the upper layer part 4, the permeability of the oil is good, but the hole diameter of the upper layer part 4 is small, so the oil coating amount can be controlled according to the hole diameter, thereby maintaining a constant quantity. The upper layer part 4 is small in hole diameter, so the coating quantity of the oil is controlled according to the hole diameter and held proper. Consequently, oil is applied stably for a long period and the roller staining occurs only after a sufficient number of copies are taken.
