Abstract

PURPOSE:To increase the attraction between a toner image and a form to reduce the occurrence of toner scattering for light emission of a flash lamp, by giving the electric charge having the same polarity as that for transfer to transfer data from the rear side of the form just before the flash fixing in a copying machine, a printer, or the like of the electrophotographic system. CONSTITUTION:A drum type photosensitive plate 7 is charged by a main charger 3, and transfer data is formed on the photosensitive plate 7 by a laser power 4 and a developing equipment 5, and the electric charge is given from the rear side of a form P by a transfer charger 6 to transfer transfer data from the photosensitive plate 7 onto the form P. The form P is moved to a flash fixing part 9, and transfer data is fixed to the form P by a flash lamp, and the form P is ejected by an ejecting roller 10. The electric charge having the same polarity as that for transfer is given to transfer data just before the flash fixing by a charging charger 8 to increase the attraction between transfer data and the form, and transfer data is fixed to the form P in the flash fixing part 9.

因となるとともに定着性も低下させる原因となっていた
。また、飛散したトナーによってフラッジ−ランプの発
光音が大きくなるという欠点があった。Conventionally, in the flash fixing device of an electrophotographic copying machine printer, etc., 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 smear and the fixing part to be damaged. In addition to causing stains, the fixing performance also deteriorates. Another drawback is that the scattered toner increases the sound of the flash lamp.

間の吸着力を増加させ、フラ。The present invention solves the above problems. By applying a charge of the same polarity as during transfer to the transfer data from the back side of the paper immediately before flash fixing, the adsorption force between the toner image and the paper is increased and the image is fixed.

ニングするブラシである。The figure shows an example of an electrophotographic printer. That is, a drum-shaped photosensitive plate 7 is charged by the main charger 3, transfer data is formed on the photosensitive plate 7 by the laser power 4 and the developing device 5, and then an electric charge is applied from the back side of the paper P by the transfer charger 6 to make it photosensitive. The transfer data is transferred from the plate 7 onto the paper P. Next, the paper P is transferred to the fludge fixing unit 9, the transfer data is fixed on the paper P by a flash lamp, and the paper P is discharged by the discharge roller 10. 1 is an eraser lamp, and 2 is a brush for cleaning the photoreceptor 7.

用紙Ｐに定着する。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 an electric charge of the same polarity as that during transfer to the transferred data immediately before the fluff is fixedly attached, to strengthen the adsorption force between the transferred data and the paper 7, and the fluffy fixedly attached portion 9 The transferred data is fixed on the paper P.

定性を図ることができる効果を有するものである。As explained above, the present invention performs flash fixing by applying an electric charge of the same polarity as that during transfer from the back side of the paper as a pre-process of constant fixation using a flannelette.
The adsorption force between the transferred data and the paper is strengthened when the flanges stick to the paper, preventing toner from scattering when the fludge lamp is emitted, resulting in higher quality printed data and lower noise and stability of the device. It is effective.
