BELT TUBULAR BODY FOR IMAGE FORMING APPARATUS, BELT EXTENDING DEVICE, AND IMAGE FORMING APPARATUS

摘要

<P>PROBLEM TO BE SOLVED: To provide a belt tubular body for an image forming apparatus, the tubular body suppressing discharge of an internal surface. Ž<P>SOLUTION: The belt tubular body for the image forming apparatus is composed of a base material that has the internal surface and an external surface opposite to it. The base material contains at least insulation resin and a conductive agent. The internal surface has an area of conductive metal oxide or metal. It is preferable that the coverage A% of the area of the conductive metal oxide or metal occupying the internal surface satisfy the relational expression: 4≤A≤15. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
