  • Publication number: 20140086652
    Abstract: The present invention provides a fixation member which exhibits enhanced wear resistance and sliding property between the peripheral surface of the fixation member and a pressure member, which can reduce driving torque at a fixation unit, and which does not cause stick slipping even in a high-load operational mode, and a fixation apparatus having the fixation member. The fixation member employed in a fixation unit of the fixation apparatus has a metallic substrate having at least one layer of an electrocast seamless belt, and a slide layer disposed on the inner peripheral surface of the metallic substrate, wherein the slide layer is formed of at least one species of the group consisting of a polyamide-imide resin and a polyimide resin, and a fluororesin; the slide layer has a fluororesin content of 27.5 mass % to 50 mass %; and the slide layer has a surface roughness Ra of 0.4 ?m or less.
