Abstract:
An image forming apparatus includes an image bearing member, a transfer roller, a power feeding roller, a power source, and a controller. The controller is configured to execute a cleaning mode of cleaning the power feeding roller by applying a bias from the power source to the power feeding roller to transfer toner adhering on the power feeding roller to the image bearing member in a non-image formation period. The controller executes the cleaning mode in such a manner that, when a rotation time in which the transfer roller rotates one round is t1 and a rotation time in which the power feeding roller rotates one round is t2, the cleaning mode comprises a period equal to or longer than (t1+t2) in which an opposite polarity bias having an opposite polarity to the transfer bias is continuously applied from the power source to the power feeding roller.

Claim (Index 2):
The image forming apparatus according to  claim 1 , wherein the controller is configured to execute the cleaning mode in such a manner that the cleaning mode comprises a period equal to or longer than (t 1 +t 2 ) in which a same polarity bias having the same polarity as the transfer bias is continuously applied from the power source to the power feeding roller while rotating the image bearing member, the transfer roller, and the power feeding roller.
