<p>In an image forming apparatus, an intermediate transfer belt (200) is made of a resin film and is supported by a plurality of rollers (210, 211, 212, 213). A driving roller (211) that is one of the plurality of rollers (210, 211, 212, 213), drives the intermediate transfer belt (200), and also functions as an opposing unit with respect to a secondary transfer roller (210). The driving roller (211) is made of metal, and applies a bias to at least secondary transfer units, at least at a time of performing primary transfer to a plurality of image bearing bodies (201, 202, 203, 204).</p> |
