Document Type and Number:
Japanese Patent JP2007262387
Kind Code:
A
Abstract:
To provide a low hardness vulcanized rubber molded article which can be used as a roller, a belt, or the like for the charging, development, transfer or the like of an electrographic process used in a copying machine, a printer, or the like, has a good volume resistivity in a semi-conductive region and good migration resistance.
This rubber composition comprises an epichlorohydrin-based polymer rubber in an amount of ≥20 wt.% per 100 wt.% of a rubber component, and an oxidized mineral oil and a vulcanizing agent in amounts of 0.1 to 20 pts.wt. and 0.1 to 10 pts.wt., respectively, per 100 pts.wt. of the rubber component.
