Abstract
A fixing device includes a fixing roller and a pressure roller. The fixing roller and the pressure roller each have an elastic layer formed between a core bar and a release layer, which release layer serves as a surface of the fixing roller and the pressure roller. The pressure roller has a lower Asker-C hardness than that of the fixing roller, and has a greater micro rubber hardness than that of the fixing roller. This prevents the surface of the pressure roller from deteriorating in a short period of time.
