Abstract
An oil application device having an oil application amount control layer bonded to an oil retaining member for retaining application-use silicone oil using the mixture of adhesive and mixture-use silicone oil. The ratio (V.sub.KS)/(V.sub.TS) of a viscosity (V.sub.KS) of the mixture-use silicone oil at 25.degree. C. to a viscosity (V.sub.TS) of the application-use silicone oil at 25.degree. C. ranges from 50/1 to 1/10. By using the oil application device, releasing oil can be applied to a thermal fixing roller uniformly. The oil application amount control layer does not peel off or is not displaced during operation, and no oil exudes during nonuse.
