A method of increasing the lubricity of an extrusion component, the method comprising: functionalizing a surface of a wall of an extrusion body with PDA material to form a PDA treated surface; coating the PDA treated surface with a lubricious material; and heat treating the wall of the extrusion body for a time and a temperature sufficient to cause the lubricious material to adhere to the PDA material, and for the PDA material to adhere to the wall; wherein the surface of the wall is optionally oxidized prior to the functionalizing. Also an extrusion component comprising: an extrusion body comprising an inlet face and an outlet face, the body comprising a base structure comprising an internal wall defining at least a portion of an extrusion pathway from the inlet face to the outlet face, wherein at least part of the internal wall comprises a lubricious coating that defines at least part of the extrusion pathway.

A fixing belt includes: a base having an endless shape; and a resin layer covering a surface on an inner peripheral side of the base, the resin layer comprising a resin and a filler, and having a second surface opposite to a first surface facing the base, the second surface having cell structures, and being roughened with the filler. When arithmetic mean roughnesses of the second surface in the central region X and the end regions Y and Z are defined as RaX, RaY and RaZ respectively, a difference between RaX and RaY, a difference between RaY and RaZ, and a difference between RaX and RaZ are all 0.1 μm or smaller, and a coefficient of variation of areas of the cell structures contained in each of the central region X, and end regions Y and Z is 25% or smaller.
