Conductive rubber roller and transfer roller |
摘要 |
A conductive rubber roller having a rubber layer on a conductive core material. The rubber composition constituting the rubber layer contains a rubber component and a filler. The rubber component contains an epichlorohydrin rubber. The filler includes carbon black (A) having a nitrogen adsorption specific surface area (N2SA) of 20 m2/g to 40 m2/g and having a dibutyl phthalate (DBP) oil absorption of 80 ml/100 g to 100 ml/100 g and carbon black (B) having a nitrogen adsorption specific surface area (N2SA) of 15 m2/g or less and having a dibutyl phthalate (DBP) oil absorption of 40 ml/100 g or less. The carbon black (A) is in a content of 10 parts by mass to 30 parts by mass and the carbon black (B) is in a content of 20 parts by mass to 60 parts by mass or less, based on 100 parts by mass of the rubber component.
