Conductive roll and method of producing the roll.

摘要

A conductive roll (10) including a conductive shaft (12), a conductive rubber foam layer (14) formed on an outer circumferential surface of the conductive shaft (12), and a semi-conductive solid rubber layer (16) formed on an outer circumferential surface of the conductive rubber foam layer (14). The conductive roll (10) is produced by forming a cylindrical laminar body (24) which gives the conductive rubber foam layer (14) and semi-conductive solid rubber layer (16), and simultaneously vulcanizing and foaming the laminar body (24) in a mold (26) in which the conductive shaft (10) is placed in position.
