Abstract
Official abstract text for this publication.
An image forming apparatus includes a first heating rotator and a first pressing rotator forming a fixing nip fixing a non-fixed toner image formed in an image forming portion onto a sheet, a second heating rotator and a second pressing rotator forming a heating nip heating the fixed toner image on the predetermined sheet that has passed through the fixing nip, a first rubbing member keeping a range of the first heating rotator contactable with the sheet at a predetermined surface roughness by rubbing a surface of the first heating rotator, and a second rubbing member keeping a range of the second heating rotator contactable with the sheet at a surface roughness smaller than the predetermined surface roughness by rubbing a surface of the second heating rotator.
