Abstract

Abstract PURPOSE:To make the mechanism small-size and make coating uniform and reduce consumption of the release oil (agent), by providing a mechanism which applies the release agent to the fixing rolle through the tetrafluoroethylene resin porous film. CONSTITUTION:The mechanism is so constituted that release agent 1 may be supplied to fixing roll 7 through tetrafluoroethylene resin porous film 3. In this case, since holes of tetrafluoroethylene resin porous film 3 are very small such as 0.01mu-10.0mu, release oil 1 supplied to porous film 3 passes through holes and exudes in a very low speed. By selecting the hole diameter of porous film 3, viscosity of release oil 1 is lowered to make release oil 1 easy to exude according as the temperature of the coating mechanism rises. Further, when the form of the porous film is molded as shown by the figure or oil impregnating materials are inserted into the porous film, release oil 1 can be supplied uniformly.
