PURPOSE:To prevent the oil contamination in the end parts of paper with respect to a fixing roller having an oil absorbing layer by laminating long fiber pulp paper coinciding with the axial direction of a mandrel and nonwoven fabrics having no fiber directivity alternately and fixing the same to the mandrel. CONSTITUTION:An oil absorbing layer 1 is provided to a mandrel 2 of a roller, whereby a cleaning roller of a fixing roller for electrophotographic copying is obtained. The layer 1 is formed by laminating long fiber pulp paper 3 coinciding roughly with the axial direction of the mandrel 2 and nonwoven fabrics 4 having no fiber directivity alternately from the outer side, and is fixed to the mandrel 2. The oil contamination of the paper passing through the fixing roller is prevented by using such cleaning roller. The width of the paper to be fixed varies. Even with the paper of varying widths, the paper 3 of the layer 1 absorbs the oil on the surface into the central part and further absorbs the oil to the inside part of the layer 1; therefore the contamination of the end parts of the paper is prevented during fixing stage. |
