Abstract
An image-forming apparatus includes an image-forming unit, a fixing device including a heating rotator and a pressure member forming a nip portion together with the heating rotator, and a bias-applying unit applying bias to the heating rotator. Image forming modes each having a time interval between a preceding recording material and a succeeding recording material which is different from each other can be performed. A control unit executes a first control while the recording materials are being conveyed at the nip portion, and a second control while the recording materials are not being conveyed at the nip portion due to the time interval. A switching time in the image forming mode in which the time interval is a first time interval is determined to be longer than in the image forming mode in which the time interval is a second time interval shorter than the first time interval.
