Claims
- 1. A printer comprising:
an exposure device operable to generate a light beam corresponding to image information; a photosensitive body on which a latent image is formed based on the light beam delivered from said exposure device; a charger operable to charge said photosensitive body; a developer operable to convert the latent image formed on said photosensitive body into visible image using toner particles; a belt on which the visible toner image is transferred; and a fixing device for fixing the toner image onto a recording medium, said fixing device comprising:
a heating roller comprising magnetic metal; a fixing roller disposed parallel to said heating roller; an endless belt bridging said heating roller and said fixing roller; a press roller pressed to said fixing roller via said endless belt and the recording medium; and a coil core operable to produce magnetic fields disposed adjacent to said heating roller; wherein said fixing roller is coated with a resilient layer having a thickness of 3-8 mm and a hardness of 15-50° by Asker hardness.
- 2. A printer comprising:
an exposure device operable to generate a light beam corresponding to image information; a photosensitive body on which a latent image is formed based on the light beam delivered from said exposure device; a charger operable to charge said photosensitive body; a developer operable to convert the latent image formed on said photosensitive body into visible image using toner particles; a belt on which the visible toner image is transferred; and a fixing device for fixing the toner image onto a recording medium, said fixing device comprising:
a heating roller comprising magnetic metal; a fixing roller disposed parallel to said heating roller; an endless belt bridging said heating roller and said fixing roller; a press roller pressed to said fixing roller via said endless belt and the recording medium; and a coil core operable to produce magnetic fields disposed adjacent to said heating roller, wherein said endless belt includes at least one of a heating layer having a thickness of 20-50 μm, a resilient layer having a thickness of 150-300 μm and a resin layer having a thickness of 20-150 μm.
- 3. A fixing device comprising:
a heating roller comprising magnetic metal; a fixing roller disposed parallel to said heating roller; an endless belt bridging said heating roller and said fixing roller; a press roller pressed to said fixing roller via said endless belt and the recording medium; and a coil core operable to produce magnetic fields disposed adjacent to said heating roller, wherein said fixing roller is coated with a resilient layer having a thickness of 3-8 mm and a hardness of 15-50° by Asker hardness.
- 4. A fixing device comprising:
a heating roller comprising magnetic metal; a fixing roller disposed to said heating roller; an endless belt bridging said heating roller and said fixing roller; a press roller pressed to said fixing roller via said endless belt and the recording medium; and a coil core operable to produce magnetic fields disposed adjacent to said heating roller, wherein said endless belt includes at least one of a heating layer having a thickness of 20-50 μm, a resilient layer having a thickness of 150-300 μm and a resin layer having a thickness of 20-150 μm.
