Abstract
The present invention provides a transfer charger which provides an intermediate transfer belt with a sufficient transfer efficiency, does not wear in contact with an inner surface of the intermediate transfer belt, has a low frictional property, and is excellent in its friction stability and an image-forming apparatus. A transfer charger () is mounted inside the image-forming apparatus where a toner image held on an image holder () is transferred to an intermediate transfer belt () to obtain an image. The transfer charger () makes a surface contact with an inner surface of the intermediate transfer belt (), with the transfer charger () being pressed toward the image holder () owing to a pressing member (). The transfer charger () is a sheet material consisting of a resin composition containing 100 parts by weight of non-injection-moldable ultra-high-molecular-weight polyethylene resin, 2 to 15 parts by weight of electrically conductive carbon, and 0.5 to 5 parts by weight of at least one powder selected from among PTFE resin powder, graphite powder, and silicone resin powder.
