Title:
CONDUCTIVE RUBBER ROLLER
Document Type and Number:
WIPO Patent Application WO/2005/059657
Kind Code:
A1
Abstract:
A conductive rubber roller capable of inhibiting the attachment of toner to roller parts while retaining desirable electrical properties is provided without pass through complex production procedure. There is provided a conductive rubber roller characterized in that at least a roller surface consists of a rubber composition comprising 100 parts by mass of rubber component and 0.01 to 20 parts by mass of plasticizer wherein the difference between solubility parameter (SP value) (A) of main constituent of the rubber component and solubility parameter (SP value) (B) of main constituent of the plasticizer, (A)-(B), is 0.9 or greater. It is preferred that the rubber composition be a solid rubber or sponge rubber and that the main constituent of the rubber component be an epichlorohydrin rubber. At least one component whose solubility parameter (SP value) (B) falls within the range of 5.0 to 8.5 can appropriately be used as the plasticizer.
