Abstract

PURPOSE:To prevent toner offsetting and winding of an image support material on rollers by blocking the excess portion of the specified offset-preventing liquid by the specified high-viscosity offset-preventing liquid to be intermittently or continuously supplied to the contact part between a blade member and a fixing roller. CONSTITUTION:Silicone oil 13 for offset preventing of 0.5-10 Poises in viscosity at ordinary temperature in an oil pan 12 is coated on the surface of a heat-fixing roller 1 by way of heat-resistant felt 14, a heat-resistant cloth 15 and a coating roller 16, and its excess portion is blocked by a blade 20 which is held contacted with the roller 1 in its forward direction. On the other hand, the paste-form high-viscosity offset-preventing liquid 18 of 100 Poises or more in viscosity at ordinary temperature which is contained in a vessel 17' and comprises compounding silica in silicone oil is coated intermittently or continuously by gravity on the surface of the roller 1 by way of felt 17 and the blocking of the excess amount of the oil 13 by the blade 20 is smoothly accomplished without generating any vibration and the like, thus the offsetting of toners to the roller and the winding of an image carrire C such as paper on the roller are prevented.
