Abstract
A fixing belt and a fixing device suppress charging of the fixing belt and permit securing of a withstand voltage of secondary parts of the fixing belt are provided in addition to a heater. The fixing belt is formed of a tubular endless fixing film including, in order from an inner peripheral side of the film, a base layer, an elastic layer, and a release layer. A surface resistivity of the fixing belt measured from the base layer side is 7 [LOG Ω/sq.] or more and 10 [LOG Ω/sq.] or less.
