Cleaning system, fixing device, and image forming apparatus incorporating same

摘要

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 opposite the fuser member. The fuser member and the pressure member are pressed against each other to form a fixing nip therebetween through which a recording medium is conveyed as the fuser member and the pressure member rotate together. The cleaning system cleans the pressure member, and includes a cleaning web, a web supply mechanism, and a controller. The cleaning web at least partially contacts the pressure member to wipe the pressure member. The cleaning web is mounted on the web supply mechanism to be released into contact with the pressure member. The controller is operatively connected with the web supply mechanism to control an amount of supply of the cleaning web.
