<P>PROBLEM TO BE SOLVED: To provide a conductive grease capable of affording a stably and low bearing resistance to an enclosed bearing, and to provide a rolling bearing enclosing the grease, an image forming apparatus and a fixing apparatus using the rolling bearing. <P>SOLUTION: The conductive rolling bearing 1 used for an image forming apparatus and a fixing apparatus holds a plurality of rolling elements 4 between raceway surfaces 2a, 3a of an inner ring 2 and an outer ring 3, and the conductive grease 7 is enclosed between the raceway surfaces. The conductive grease 7 contains carbonic conductive material particles such as carbon black particles, graphite particles or the like, and an amine salt of polyether phosphate or an amidoamine salt of a polyester acid is contained in an amount of 10-100 wt.% based on the carbonic conductive material particles. <P>COPYRIGHT: (C)2009,JPO&INPIT |
