Abstract
A fixing device includes a fixing member, a member disposed opposite the fixing member, a rubbing member, a detector, and a rubbing operation controller. The fixing member fixes a toner image on a recording medium. The rubbing member rubs the fixing member to maintain a surface of the fixing member in optimum condition of the fixing member. The detector detects vibration of the rubbing member. The rubbing operation controller controls rubbing the fixing member with the rubbing member. The rubbing operation controller controls a rubbing rotation speed and a rubbing force in response to at least the vibration of the rubbing member as a trigger.
