An oil transfer component for transferring oil to a roll (2) in a fuser system of a copying machine, such as a plain paper copier or laser printer, is formed of contiguous layers (17a, 17b, 17c etc.) of porous PTFE sheet material. Typically there are from three to twenty layers. The component may be formed by winding turns of a single length around a core (e.g. in the case of a roller (10)) or may be formed of separate sheets (when a pad is made). The porous PTFE may be formed from particles of granular-type PTFE fused to form a porous integral network; or may be a porous expanded PTFE. The oil transfer component is convenient to produce and has good oil delivery and toner wiping properties, and resists puddling of oil. <IMAGE> |
