Abstract:
In order to prevent interference between a primary transfer bias voltage and a secondary transfer bias voltage, and to prevent occurrence of an image defect due to interference between these bias voltages, an image forming apparatus includes a plurality of primary transfer rollers, an intermediate transfer belt, a drive roller, a secondary transfer roller, and a rectifier roller. A primary transfer bias voltage of a polarity opposite to the polarity of toner is applied to a primary transfer bias applying unit. A secondary transfer bias voltage of a same polarity as the polarity of toner is applied to the drive roller. The rectifier roller is disposed between a most-downstream primary transfer roller and the drive roller. A bias voltage of the same polarity as the polarity of the primary transfer bias voltage or the polarity of the secondary transfer bias voltage is applied to the rectifier roller.

Claim (Index 6):
The image forming apparatus according to  claim 5 , wherein\n when it is assumed that a distance between the most-downstream primary transfer roller and the contact member along the inner peripheral surface of the intermediate transfer belt is a (mm), a distance between the contact member and the support roller along the inner peripheral surface of the intermediate transfer belt is b (mm), and a distance between the support roller and the sub contact member along the inner peripheral surface of the intermediate transfer belt is c (mm), the image forming apparatus satisfies a relationship: a<b and c<b.
