<P>PROBLEM TO BE SOLVED: To provide a semiconductive roller that has ample bonding force between a semiconductive elastic body and a surface resistance adjustment layer and is uniform in electrical resistance, and to provide an electrophotographic apparatus that has the semiconductive roller. <P>SOLUTION: A manufacturing method is provided for the roller that is integrally formed from a conductive shaft body (rotary shaft body) 1, a semiconductive elastic body 3 covering the semiconductive shaft body 1, and a surface resistance adjusting layer 4, formed on the surface of the semiconductive elastic body 3 and that is used in an electrophotographic apparatus, such as copying machines, FAXs, or printers. The method includes the step of forming a SiO<SB>2</SB>layer 5 on the surface of the semiconductive elastic body 3, and the step of forming a surface resistance adjustment layer 4 on the outside of the SiO<SB>2</SB>layer 5. <P>COPYRIGHT: (C)2007,JPO&INPIT |
