Abstract: A fixing device includes: a laser radiating section for radiating laser light to a sheet so that a toner image on the sheet is fixed to the sheet, an optical sensor, and a smoke detecting section. The optical sensor includes a light radiating section for radiating light with a predetermined wavelength and a light receiving section for receiving the light with a predetermined wavelength so as to output a signal corresponding to a received amount of the light with a predetermined wavelength. The light radiating section and the light receiving section are positioned in such a manner that the light radiating section and the light receiving section face each other with a light path of the laser light therebetween, and light radiated from the light radiating section crosses the light path of the laser light and then reaches the light receiving section. The smoke detecting section detects smoke in the fixing device based on the signal. Thus, the laser fixing device can detect smoke with high accuracy.

Abstract: A recording sheet has an unfixed toner image that is formed thereon, and is conveyed to a fixing device. A surface reforming device of the fixing device performs surface reformation for the surface of the toner on the recording sheet by, for example, plasma irradiation or the like, thereby generating a polar group of a hydrophilic property on the surface of the toner. Next, the recording sheet is conveyed to a laser irradiation portion by a recording sheet conveyance device to be irradiated with a laser, in which the toner is fused to be fixed to the recording sheet. The toner on the recording sheet is subjected to surface reforming treatment, thus having increased affinity (adhesion force) with the recording sheet, so that it is possible to secure favorable fixability without pressing.
