ABSTRACT:
A fixing device for an electrophotographic copying machine which includes a pair of rollers forming a nip therebetween through which the copy paper passes and an applicator which is capable of feeding a sufficient quantity of offset-preventing liquid only to the portion of the rollers where the leading end of the copy paper, will contact with the supply of offset-printing liquid to the remaining portion of the rollers being minimized to a quantity necessary for the preventing of offset. The consumption of offset-preventing liquid is reduced and the swelling of the silicone rubber coatings on the rollers, when used, is inhibited.
