摘要： A fixing apparatus for an image forming apparatus of the present invention includes: a rotatable heat roll; a heat-resistant elastic member fixedly disposed to form a nip section in contact with an outer circumferential surface of the heat roll, the heat-resistant elastic member being impregnated with a liquid release agent which is supplied to the nip section; and a porous fluororesin film formed by sintering a fluororesin powder for coating a surface of the heat-resistant elastic member coming in contact with the heat roll so that the release agent can be supplied by a predetermined amount while permeating through the film. The porous fluororesin film may include: a film formed by using metal fibers, glass fibers, or the like as a supporting member thereof, and a film formed by applying a gelled dimethyl silicone oil at least to a single surface of the film.

摘要： A fixing unit has a fixing roller and an endless belt. When a recording sheet bearing a toner image not yet fixed passes between the fixing roller and the endless belt, the fixing unit fixes the toner image onto the recording sheet in the nip area. The endless belt is a film-like belt consisting of a base film and a layer on the base film, the layer being made of a composite material containing porous material and elastomer. A fixing unit is thus provided which is free from the problems of image offset and lifetime shortening, and can realize the increase of fixing speed and/or size reduction.

摘要： A liquid metering and coating assembly for use in a thermal toner fixation unit of a plain paper copier or printer. The assembly consists of a release oil-supply roll having a compliant and flexible porous permeation control layer and a cleaning blade. The cleaning blade is mounted so as to contact the surface of the permeation control material. The cleaning blade removes excess toner and other incidental debris from the surface of the permeation control layer thereby providing a freshly cleaned surface from which controlled amounts of release oil are uniformly coated onto the surface of an adjacent contacting roll.
