Abstract
Apparatus for fixing toner images carried on a long footage of continuous web such as rolled paper or folded paper, uniformly but intermittently from end to end of the web. The apparatus includes a heating roller and a second roller and control circuitry. During fixation, the image bearing surface of the web is urged against the heated roller which is rotated to move the web, and during the intermission of fixation, the web is disengaged from the heating roller. Preferably, when the web is urged against the heating roller and/or when the web is disengaged from the heating roller, rotation thereof is stopped and the web is maintained in pressure contact with the stopped heating roller for a predetermined time.
