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 4):
The fixing device according to  claim 1 , wherein\n the cleaning member is a cleaning roller, the second roller is formed in a shape that an outer diameter is gradually increased from a center portion in a rotation axis direction of the second roller toward an outer end portion, and the cleaning roller is formed in a shape that an outer diameter is gradually reduced from a center portion in a rotation axis direction of the cleaning roller toward an outer end portion correspondingly to a shape of the second roller.
