とする電子複写機。 A photoreceptor with a rectifying property that conducts only charges of polarity opposite to that of the developer image between the ground and the polarity of the developer image formed on the surface of the photoreceptor from the back side of the image support, facing the photoreceptor. a transfer charger for transferring the developer image onto the image support by emitting a transfer corona having a polarity opposite to that of the image support; A peeling charger for peeling off the image support from the surface of the photoreceptor and a static elimination lamp for neutralizing the surface of the photoreceptor after the image support has been peeled off are arranged, and the transfer charger, peeling charger and static elimination lamp are activated simultaneously by the image forming start operation. At the same time, the photoreceptor has a rectifying property that removes only charges having a polarity opposite to the polarity of the developer image formed on the surface of the photoreceptor by the static elimination lamp, and the developer of the photoreceptor is An electronic copying machine characterized in that the leading end of the image forming part is set at a part that sequentially undergoes at least the above-mentioned transfer, peeling charger and discharge lamp processes from the time of copying the first sheet.
