Abstract
A fixing device includes a feeding roller for feeding a belt-shaped cleaning member which has been rolled up, and a winding roller for taking up the cleaning member which has been fed from the feeding roller and cleaned a surface of the fixing roller, the winding roller being provided so as to pressure-contact the feeding roller. The winding roller is rotated by a time control due to a control portion so that a sum of a feed amount of the cleaning member which is fed by the feeding roller at one feeding occasion, and a take-up amount of the cleaning member which is taken up by the winding roller at one take-up occasion, is equal to or more than a double of a length Ln of a nip section.
