A fixing device includes a heat rotating body, a pressure applying rotating body, a heat leveling rotating body for equalizing temperature distribution of a rotating body which is one of the heat rotating body and the pressure applying rotating body, and a brush rotating body which includes a plurality of fibers for cleaning a surface of the heat leveling rotating body. A switching unit switches a contact state between the heat leveling rotating body and the rotating body which is the one of the heat rotating body and the pressure applying rotating body, between a state in which the heat leveling rotating body makes contact with the rotating body and a state in which the heat leveling rotating body is separated from the rotating body, by moving integrally the heat leveling rotating body and the brush rotating body making contact with each other. |

1. A fixing device comprising:
a heat rotating body being heated by a heat part, a pressure applying rotating body for fixing a inner image on a recording medium, by forming a nip portion by making contact with the heat rotating body with pressure, and holding and conveying the recording medium carrying the toner image by the nip portion, a heat leveling rotating body for equalizing temperature distribution in the direction of a rotation shaft of a rotating body which is one of the heat rotating body and the pressure applying rotating body, a brush rotating body which includes a plurality of fibers for cleaning a surface of the heat leveling rotating body, and a switching unit for switching a contact state between the heat leveling rotating body and the rotating body which is the one of the heat rotating body and the pressure applying rotating body, between a state in which the heat leveling rotating body makes contact with the rotating body, and a state in which the heat leveling rotating body is separated from the rotating body, by moving integrally the heat leveling rotating body and the brush rotating body making contact with each other. |
