Abstract:
1. A conductive member, comprising: a long conductive supporting body; an electrical resistance adjusting layer, disposed on the outer circumferential surface of the conductive supporting body and having a reduced diameter section at either end; and a pair of gap maintaining members which are respectively fitted onto said reduced diameter sections of the electrical resistance adjusting layer, wherein the outer circumferential surfaces of said gap maintaining members have a height differential with respect to the outer circumferential surface of said electrical resistance adjusting layer, in such a manner that when abutted against an image carrier, a prescribed gap is formed between the outer circumferential surface of said image carrier and the outer circumferential surface of said electrical resistance adjusting layer, and taking X wherein a ratio B/A between an outer diameter B of the reduced diameter sections on either end of said electrical resistance adjusting layer, and an outer diameter A of said electrical resistance adjusting layer, is 0.87 to 0.97.
