Abstract: PURPOSE:To provide a flash fixing device without the lowering of fixing performance of toner to recording paper because of no generation of soil of a glass plate caused by the adhesion of toner by setting the surface resistance of at least one face of the glass plate opposed to the recording paper, to a specified value. CONSTITUTION:The flash fixing device is formed out of a heating source for heating toner 5 developed on recording paper 4 by flashlight to fix the toner 5 on the recording paper 4, and a glass plate 3 covering a part of the heating source and opposed to the recording paper 4. The surface resistance of at least one face of the glass plate 3 is to be 10 OMEGA/square inch or less. With the surface resistance of at least one face of the glass plate 3 thus reduced to prevent the substantial electrification of the glass plate 3, the grain of the toner 5 does not electrostatically adhere to the glass plate 3, so that the soil of the glass plate 3 is not generated. The surface resistance of the glass plate 3 has to be 10 OMEGA/square inch or less at least on one face, but it is desirable to be 10 OMEGA/square inch or less, further desirably 10 OMEGA/square inch or less.
