A tilting pad stripper for stripping copy sheets from a wetted fuser roll surface. A stripping shoe 32 is formed with a bottom surface 36 which is arcuate in shape complimentary with the curve of the surface of fuser roll 16. The distance between the pivot axis at knife edge 34 and the lead edge 37 of stripping shoe 32 is approximately 58% of the arcuate length of shoe 32. The bottom surface 36 is made from a material which is wetted by the oil in order to develop the oil film necessary for proper action. Copy sheet S is stripped from the surface of fuser roll 16 by the stripping action exerted from stripping shoe 32 which rides on an oil film OF on the surface of the fuser roll. Oil film OF supports the bearing load of stripping shoe 32 such that the impact of the stripper copy sheet S does not drive stripping shoe 32 into physical contact with top layer 22 of fuser roll 16 which is delicate and easily damaged.
