PROBLEM TO BE SOLVED: To provide an elastic member realizing the low coefficient of friction without damaging the fundamental characteristics of an elastomer becoming a substrate and excellent in abrasion resistance, and the electrophotographic apparatus. SOLUTION: In the elastic member including the elastomer becoming the substrate used in the region brought into slide contact or rotary contact with a partner member, at least the contact part with the partner member has a layer comprising flexible diamond-like carbon and the Haydon type coefficient of static friction of a paired glass surface becomes large along with a friction speed, the coefficient of static friction at a friction speed of 6,000 m/min is not more than 2.5, and the fluctuation of the coefficient of static friction at the friction speed of 1,000-6,000 mm/min is not more than 1.0. |
