Abstract: A matting liquid coating section supplies a matting liquid to an outer peripheral surface of a pressing roller. At the matting liquid coating section, a web, that is a non-woven fabric or the like and in which is seeped a matting liquid formed from a liquid (silicon oil or the like) in which matting agent particles are dispersed at a predetermined concentration, is trained around a first rod and a second rod, and is made to abut an outer peripheral surface of the pressing roller while running along the outer peripheral surface. The matting liquid is transferred once to the outer peripheral surface of the pressing roller, and the matting agent particles that adhere to the roller surface are again transferred onto a surface of a recording medium.
