<P>PROBLEM TO BE SOLVED: To provide a conductive rubber roller in which variations in resistance caused by the deterioration of a hydrin rubber occurring by long-term energization and further the mounting properties of a roller surface are reduced, especially the conductive rubber roller made of foam, in the conductive rubber roller, such as a transfer roller, a conductive one, or a development one. <P>SOLUTION: The conductive rubber roller in which a rubber layer made of foam is formed on a conductive core contains 1.0-10.0 pts.mass magnesium oxide to 100 pts.mass polymer content in the rubber material of the rubber layer, 1.2-3.0 pts.mass active zinc oxide, 2.0-5.0 pts.mass 2-mercapto benzimidazole, and 5-100 pts.mass epichlorohydrin rubber in 100 pts.mass polymer content in the rubber material of the rubber layer. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
