Abstract:
A fixing unit includes a heating roll, an endless belt and a pressing body having a hard pressing member and a soft pressing member. The hard pressing member is placed on a downstream of a passage direction of a record medium in a press contact part and forms higher hardness than an elastic layer of the heating roll. The soft pressing member is placed on an upstream of the passage direction from the hard pressing member, and forms lower hardness than the elastic layer. The press contact part is formed in a state in which a first press contact portion of the hard pressing member is longer than a second press contact portion of the soft pressing member. The hard pressing member has an end part opposed to the heating roll on the upstream. The end part has a face approaching the heating roll from the upstream to the downstream.
