Abstract
The fixing apparatus prevents transfer paper from sticking or jamming. This fixing apparatus is intended to fix polymerized toner on transfer material and has a heating roller and a pressure roller. The difference in hardness between the heating roller and pressure roller is 5 through 10 degrees in AskerC, and the hardness of the pressure roller is higher than that of the heating roller. A fixing nip portion, convex-shaped on the side closest to the heating roller, is formed between the heating roller and pressure roller and the nip pressure of the fixing nip portion is 24.5 N/cm or more.
