Abstract:
A transfer roller includes a support, a foamed elastic layer disposed on the outer peripheral surface of the support, and a surface resin layer that covers the outer peripheral surface of the foamed elastic layer and contains polyimide or polyamide-imide. Bubbles contained in a central portion in the roller axial direction have a shape crushed in the thickness direction of the foamed elastic layer as compared with bubbles at both ends in the roller axial direction.
