Abstract

PURPOSE:To fix the toner by pressure uniformly over the entire surface of a recording material by providing a coating amount control means which coats the release liquid by a coating means less in a region of lower pressure than in a region of higher pressure. CONSTITUTION:This device is so arranged as to adjust the coating of oil on the surfaces of fixing rollers 11, 12 by changing the holding down pressure of a felt member 2. The member 2 impregnated with release liquid is rubbed on the surfaces of the rollers 11, 12 in contact therewith in order to coat the release liquid on the surfaces of the rollers 11, 12 and to clean the rollers, and the pressure to be exerted upon the member 2 is regulated by providing openings on both side of a spring member 4 of a holding member 3 which holds the member 2 or notching the spring member 4 on both sides alone, whereby the coating amount of the oil on the surfaces of the rollers 11, 12 is controlled.
