Abstract
In the present invention, the fixing device for fixing toner images on a sheet comprises a LED array 1 provided with a plurality of LEDs and a cyrindrical lens 2. The cyrindrical lens 2 is arranged along the LED array 1 to condense the light emitted from the LED array 1 onto the surface of the sheet 3. Therefore, the toner image 8 is fused via heat of the condensed light of the LED array 1 condensed by the cyrindrical lens 2, such that the toner image 8 is fixed onto the surface of the sheet 3.
Claims18
A fixing device for fixing toner images on a paper comprising:
- light-emitting diode array provided with plurality of light-emitting diodes;
- and
- condensing means for condensing the light emitted from said light-emitting diode array onto said toner images on the paper.
