FIG. 1 shows an electronic copying machine using a fixing device according to the present invention, and numeral 1 in the figure is the main body. On the upper surface of this main body 1, there is provided a manuscript mounting table 2 that moves forward and backward in the direction of the arrow.
A drum-shaped photoreceptor 3 that rotates in the direction of the arrow in synchronization with the stand 2
An exposure system 6 including a lamp 4, a focusing film transmitter 5, etc. is provided between the photoconductor 3 and the original table 2. A certain original is illuminated and the reflected light is guided onto a photoreceptor 3 to form an image of the original. Is this IF around the photoreceptor 3?
A developing device 2, a transfer charger 8, a stripping charter 9, a cleaning device 10, a static elimination lamp 11, and a stripping charter 12 are arranged in one row along the rotational direction of the photoreceptor 3 from the image position.
