Abstract
A fixing apparatus includes a first rotatable member configured to heat, in a fixing nip, an unfixed toner image formed on a sheet with a toner having a parting material. A second rotatable member cooperates with the first rotatable member to form the fixing nip. A cleaner is configured to clean the first rotatable member, and a covering member is configured to cover the first rotatable member over a range from the cleaner to an entrance of the fixing nip along a rotational direction of the first rotatable member with a gap D of not less than 0.5 mm and not more than 3.5 mm. In addition, the gap D (mm) between the covering member and the first rotatable member and the peripheral speed V of the first rotatable member (mm/s) satisfy 0.5≤D≤0.0059×V+0.72.
