A fixing device includes a rotary fuser member, a rotary pressure member, and a cleaning system. The rotary fuser member is subjected to heating. The rotary pressure member is disposed opposite the fuser member. The cleaning system includes a cleaning web, a feeding mechanism, a positioning mechanism, and a controller. The cleaning web is disposed adjacent to the pressure member to wipe the pressure member. The feeding mechanism is operatively connected to the cleaning web to feed a new, unused portion of the cleaning web toward the pressure member. The positioning mechanism is operatively connected to at least one of the cleaning web and the pressure member to position the cleaning web and the pressure member with respect to each other. The controller is operatively connected with the feeding mechanism and the positioning mechanism to control feeding and positioning of the cleaning web.
