Abstract

An image forming apparatus includes: an image forming section which transfers a toner image in accordance with image data onto a recording sheet; a first fixing device having a first fixing roller, which fixes the toner image onto the recording sheet with heat; a second fixing device having a second fixing roller, which further applies heat to the recording sheet that has been fixed by the first fixing device; a second fixing roller surface roughness prevention mechanism which prevents a roughness on a surface of the second fixing roller that has been generated due to side ends of the recording sheet being brought into contact with the surface of the second fixing roller; and a controller which controls the image forming section, the first and second fixing devices and the second fixing roller surface roughness prevention mechanism.
