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 1):
A fixing device comprising:\n a first roller; a second roller that is provided in contact with the first roller; a cleaning member that is provided in contact with the second roller to clean the second roller; a driver that drives the second roller swingingly relative to the first roller; and a controller that controls the driver, wherein the controller controls the driver to drive swingingly the second roller relative to the first roller so as to change a pressure between the second roller and the first roller and a pressure between the second roller and the cleaning member to a predetermined relationship in accordance with a position to which the second roller is driven swingingly.
