Abstract:
1. A fixing apparatus that transports a recording medium carrying a developer image on it and heats the developer image to fix into the recording medium, the apparatus comprising: a rotating body that extends in a first direction parallel to a rotational axis and generates heat; an endless belt that runs in a second direction substantially perpendicular to the first direction; a pressure roller that extends substantially parallel to said rotating body, said pressure roller being rotatable in pressure contact with said endless belt such that said endless belt is sandwiched between said rotating body and said pressure roller; and a pressure pad that extends substantially parallel to said rotating body, said pressure pad including a pressure surface that urges said endless belt against said rotating body from inside of said endless belt, the pressure surface being in an area between said pressure roller and a belt guide, the belt guide cooperating with said pressure roller and said pressure pad in holding said endless belt without tension, said belt guide including a first outer surface on a side of said belt guide substantially opposite a second outer surface of said rotating body, wherein said pressure roller and said pressure pad press said endless belt against the second surface and the first outer surface guides said endless belt to run along the first outer surface, wherein when said rotating body rotates, said endless belt is driven in rotation in such a way that the recording medium is pulled in between said rotating body and said endless belt.
