Abstract
A fixing apparatus including: a fixing roller, pressed against a printing paper at a fixing nip area, for fixing toner on the printing paper, and transporting the printing paper by undergoing rotation; an external heating section for heating a surface of the fixing roller by being brought into contact therewith; a release/contact operating section for causing the external heating section to be brought into contact with or separated from the fixing roller; and a cleaning section for cleaning the surface of the fixing roller. The release/contact operating section brings the external heating section into contact with the fixing roller at such a timing that a portion of fixing roller initially in contact with the external heating section does not make contact with the printing paper at the fixing nip area in one rotation of the fixing roller.
