Patent ID: 8396402

Claim:
A conductive roller composed of one layer a toner transport part, and the toner transport part is composed of one layer made of a vulcanized rubber composition at least on an outermost layer thereof, said vulcanized rubber composition containing a rubber component (A), highly conductive carbon black (B) having a particle diameter not less than 18 nm and less than 80 nm, an inorganic filler (C) consisting of not less than one kind of a metal oxide selected from among a group of titanium oxide, alumina and silica; a total of a content of said highly conductive carbon black (B) and a content of said inorganic filler (C) for 100 parts by mass of said rubber component (A) is not less than 10 parts by mass nor more than 60 parts by mass; the rubber component (A) contains a combination of chloroprene rubber and epichlorohydrin copolymer; the content of the chloroprene rubber for 100 parts by mass of the rubber component (A) is set to 50 to 80 parts by mass; and the content of the epichlorohydrin copolymer for 100 parts by mass of the rubber component (A) is set to 20 to 50 parts by mass.
