| 摘要 |
The present invention provides an oil application device in which an oil application amount control layer is bonded with an oil retaining member for retaining application-use silicon oil using the mixture of adhesive and mixture-use silicon oil, and in which the ratio (VKS)/(VTS) of a viscosity (VKS) of the mixture-use silicon oil at 25° C. to a viscosity (VTS) of the application-use silicon oil at 25° C. ranges from 50/1 to 1/10. By using the oil application device of the present invention, releasing oil can be applied to a thermal fixing roll uniformly. The oil application amount control layer does not peel off or is not displaced during operation, and no oil exudes during nonuse.
