Image forming apparatus

An image forming apparatus comprising:

• a plurality of photosensitive members;
• an intermediate transfer belt capable of a rotation movement and configured to be in contact with the plurality of photosensitive members to form a plurality of primary transfer portions, convey toner images primarily transferred from the plurality of photosensitive members in the plurality of primary transfer portions, respectively, to secondarily transfer the toner images to a recording material in a secondary transfer portion;
• a plurality of primary transfer members configured to be in contact with an inner peripheral surface of the intermediate transfer belt and primarily transfer the toner images from the plurality of photosensitive members to the intermediate transfer belt by being applied with a primary transfer bias;
• a plurality of electrode members configured to be in contact with the inner peripheral surface of the intermediate transfer belt without forming a nip with the plurality of photosensitive members;
• an application section configured to apply a bias with polarity opposite to the primary transfer bias to the at least one electrode member;
• and
• a control section configured to control the application section,
• wherein the plurality of photosensitive members includes a predetermined photosensitive member which is disposed furthest downstream in a moving direction of the intermediate transfer belt, and
• wherein each of the plurality of electrode members is disposed downstream, in the moving direction of the intermediate belt, of corresponding one of the plurality of primary transfer members corresponding to the plurality of photosensitive members except the predetermined photosensitive member, and is positioned closest to the corresponding photosensitive member among the plurality of photosensitive members.
