Abstract
An image forming apparatus is capable of setting a cleaning mode in which a fixing portion is cleaned by a cleaning sheet while nip-conveying the cleaning sheet in a fixing nip. When the cleaning mode is set, an image forming apparatus provides a period in which a first rotatable member and a second rotatable member are rotated in a state in which a heater is controlled so that a surface temperature Th of the first rotatable member immediately after passing through the fixing nip is kept within a temperature range of Th≦Tf, wherein Tfis a flow start point of a toner and so that a surface temperature Tp of the second rotatable member immediately after passing through the fixing nip is within a temperature range Tf≦Tp≦Tf, wherein Tfis a deformation end point of the toner.
