Abstract:
A fixing device includes a fixing belt rotatable in a predetermined direction of rotation; a pressing belt to frictionally contact the fixing belt and rotatable in a direction counter to the direction of rotation of the fixing belt; a stationary fixing pad disposed inside a loop formed by the fixing belt; a stationary pressing pad disposed inside a loop formed by the pressing belt; and a fixing belt heater disposed inside the loop formed by the fixing belt to heat the fixing belt. The fixing pad presses against the pressing pad to form a fixing nip therebetween with the fixing belt and the pressing belt interposed between the fixing pad and the pressing pad. A recording medium bearing an unfixed toner image is conveyed through the fixing nip in a state in which the unfixed toner image contacts the fixing belt.
