Abstract
A fixing device includes a fixing unit, a cleaning unit, and a controller. The fixing unit includes a pair of nipping members and a heat source that heats at least one of the pair of nipping members. The cleaning unit includes a cleaning web wound on a supply core to be supplied from the supply core and taken up on a take-up core, and a pressing roller that is pressed against one of the pair of nipping members. The controller causes the take-up core to rotate in such a manner that, when a leading portion of the cleaning web extending up to 2% of an overall length of the cleaning web from a leading end of the cleaning web is fed, a length of the cleaning web to be fed in one feeding is 10-30% larger than when a subsequent portion of the cleaning web is fed.
