Abstract:
To provide a roller device that can improve the life of a cleaning member and that enables a cleaning member to perform a cleaning operation even when a contact-pressure release operation is performed to release the contact-pressure of the second roller on the first roller and to provide a fixing device and an image forming apparatus. The cleaning member is disposed to be opposite to the first roller with the second roller being provided therebetween. Compared to a case when the second roller is placed at a first position on a side of the first roller, if the second roller is placed at a second position on a side of the cleaning roller, a pressure between the second roller and the first roller becomes smaller, and a pressure between the second roller and the cleaning member becomes larger.

Claim (Index 8):
The fixing device according to  claim 2 , wherein\n the driver is configured to drive the first roller to rotate, and the controller is configured to control the driver to perform a first drive operation in a first period to rotate the first roller in a same direction as a rotation direction in which the first roller is rotated during an image forming operation while the second roller is placed at the first position, and perform a second drive operation in a second period to rotate the first roller in the same direction as the rotation direction in which the first roller is rotated during the image forming operation while the second roller is placed at the second position.
