本発明は、電子写真方式による複写機、プリン

である。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a flash fixing device for electrophotographic copying machines, printers, and the like.

着性も低下させる原因となつていた。また、飛散
したトナーによつてフラツシユランプの発光音が
大きくなるという欠点があつた。 Conventionally, in flash fixing devices in copiers and printers that use electrophotography, the toner on the paper onto which the toner visible image formed on the photosensitive plate has been transferred is scattered when the flash lamp is emitted, causing the printed image to blur and become fixed. This causes stains on the parts and also reduces fixing performance. Another drawback is that the sound of the flash lamp becomes louder due to the scattered toner.

とするものである。 The present invention solves the above-mentioned problems by applying a charge of the same polarity to the transfer data from the back side of the paper immediately before flash fixing, thereby increasing the adsorption force between the toner image and the paper. The present invention is characterized in that it reduces the occurrence of toner scattering when the flash lamp is emitted, improves the quality of print data, reduces the noise of the device, and stabilizes the fixing performance.

クリーニングするブラシである。 The present invention will be explained below using examples. The figure shows an example of an electrophotographic printer. That is, the main charger 3 charges the drum-shaped photosensitive plate 7, the laser power 4 and the developer 5 form transfer data on the photosensitive plate 7, and then the transfer charger 6 applies electric charge from the back side of the paper P. The transfer data is transferred from the photosensitive plate 7 onto the paper P. Next, the paper P is transferred to the flash fixing section 9, the transfer data is fixed on the paper P by the flash lamp, and the paper P is ejected by the ejection roller 10. 1 is an eraser lamp, and 2 is a brush for cleaning the photoreceptor 7.

定着する。 The present invention is equipped with a charger 8 that applies charges of the same polarity as during transfer to the transfer data transferred to the paper P as a pre-fixing process again. According to the present invention, the charger 8 applies a charge of the same polarity as that during transfer to the transferred data immediately before flash fixing to strengthen the attraction force between the transferred data and the paper, and the flash fixing unit 9 applies the transferred data to the paper. It settles on P.
