摘要： PROBLEM TO BE SOLVED: To solve a problem in which: when a recording material is passed close to one side of a path, a pressure roller of a fixing device thermally expands ununiformly, and therefore variation in speed occurs for conveying a fixing film of the pressure roller; this results in generation of twisting force to the fixing film, which may cause damage to the fixing film; and suppression of damage to the fixing film and effective passing of the recording material has been desired.SOLUTION: When a recording material is detected to be passing close to one side of a path, an image forming apparatus releases pressure for fixing an image, and thereby resolves twist of a fixing film. Accordingly, damage to the fixing film is suppressed, and the recording material is effectively passed through the path.
