Abstract
The image forming apparatus includes a sheet discharge sensor that detects a recording material, a fixing device that nips the recording material to fix an unfixed toner image onto the recording material, a fixing motor that drives the fixing device, and an engine control unit that controls the fixing motor. The fixing device includes a fixing roller, a pressure unit that forms a first nip portion with the fixing roller to press the fixing roller, and a heating unit that forms a second nip portion with the fixing roller to heat the fixing roller. The first nip portion nips the recording material to fix the toner image onto the recording material. When determining that the recording material is wound around the fixing device using the sheet discharge sensor, the engine control unit continues to drive the fixing motor.
