Abstract
A fixing apparatus includes a first, heated roller and a second roller movable from spaced apart condition in their nonoperative mode into mutual pressure contact with each other for operatively fixing a toner image to a support sheet passed therebetween, and a cleaning blade maintained in continuous contact with the first roller to clean contaminating matter from its surface. In operation, the first roller is rotated through at least one full revolution prior to contact with the second roller so that residual contaminating matter can be cleaned from the first roller surface before contact with the second roller and image fixing take place.
