Abstract
Provided is a fixing device that uses an induction heating method and is capable of shortening a warm-up time period by accelerating the speed of increase in the temperature of a fixing belt. The fixing device forms a fixing nip by having a pressurizing roller pressurize a fixing roller, which is positioned inside a rotation path of a fixing belt having a hollow cylindrical shape, from outside the rotation path via the fixing belt. Given that Db is an inner diameter of the fixing belt, Dr is an outer diameter of the fixing roller, and a rate X is a value obtained by dividing the inner diameter Db of the fixing belt by the outer diameter Dr of the fixing roller, the fixing belt and the fixing roller that satisfy a relationship 0<X≦1.18 are used.
