Abstract
A fixing apparatus for fixing a toner image formed on a transfer sheet comprised of rotatable heating member having a thermo-conductive base material, a heat-resistive resilient layer provided to cover the outer surface of the thermo-conductive base material, and a heat-resistive releasing layer provided to cover the heat resistive resilient layer; and a rotatable pressure member to nip and transport the transfer sheet cooperating with the rotatable heating member, for fusing the toner image on the transfer sheet; wherein, hardness of the surface of heat-resistive releasing member measure by a micro hardness meter is 55 to 75° and the surface roughness Rz is 0.5-2.0 &mgr;m.
