  • Fixing For Electrophotography (AREA)

Abstract

PURPOSE: To fix stably for a long period of time by preventing drop of fixing efficiency due to contamination with dust or smoking of copying paper, by enveloping the light source with a tubular body having a reflecting mirror in the upper part of the light source for fixing and a transparent window in the lower part thereof.
CONSTITUTION: A reflecting mirror 11 made of gold plated thin plate is affixed to the inner wall of upper part 10a of a tubular body 10, and reflecting mirrors made of gold plated thin plate are affixed to the inner face of both side walls 12 of the tubular body 10. A light source 15 is supported in the position corresponding to the focus of the ellipse on one side of the tubular body 10, and the lower part 10b of the tubular body 10 is a transparent window, so that the radiated light passes through this window and is converged in a focus 17 of the ellipse on the other side. A copying paper 18 passes through the focus 17, and is fixed by the converging light beams 16. Since the inner face of the reflecting mirror is protected by the tubular body, the reflecting mirror will never be contaminated even if the copying paper smokes due to paper jamming, so that the fixing efficiency may be stably maintained for a long period of time.
