Abstract
A fixing apparatus includes a rotatable fixing member, a rotatable pressurizing member, a heating portion, and a circuit portion including a contact member and configured to remove electric charge from the fixing member, the contact member being in contact with the fixing member. A surface layer of the pressurizing member is electrically connected to the circuit portion via a surface layer of the fixing member. In a case where a surface resistivity of the surface layer of the pressurizing member is represented by X (Ω/□) and a surface resistivity of the surface layer of the fixing member is represented by Y (Ω/□), 4.0≤log X≤13.0, 5.0≤log Y≤14.0, log Y≥13.0−log X, and log Y≤23.0−log X are satisfied.
