PROBLEM TO BE SOLVED: To solve the problem of a fixing device of external heat system, in that adhering matter, such as toner adhering to the surface of a fixing roller, accumulates on the surface of a heating roller to be fixing unevenness, or accumulating adhering matter falls onto a recording material in a mass, resulting in image failure.SOLUTION: The pressure distribution of a heat press-contact part formed between a heating rotor and a fixing roller has an area where pressure increases after decreasing, which area is located downstream of the middle of the direction of rotation of the heating rotor of the heat press-contact part. |
