Title: Image forming device
Inventor: NAGASE HISANORI
IPC: G03G15/00
Filed: 1993-11-01
Abstract: PURPOSE:To eliminate the toner having the reverse polarity form the transferring roller and to prevent the transfer material from causing the staining on the rear side by electrifying the surface of the image carrier with the electrifier and electrically grounding the transferring roller when the transfer material is not present in the press-contact part between the image carrier and the electrifying device. CONSTITUTION:When the transfer material 17 is not present in the press-contact part of the image carrier (photoreceptor) 21 with the transferring roller 18, the surface of the photoreceptor 21 is electrified by the electrifier 11 and reaches the press-contact part with the transferring roller 18 after passing through the developing device 14. Since the transferring roller 18 is electrically grounded, the electric field is generated so that the toner having the reverse polarity is oriented toward the surface of the photoreceptor 12 from the transferring roller 18. Thus, the toner having the reverse polarity stuck on the transferring roller 18 is moved to the photoreceptor 21 by the electric field, and as the duration time of this state lasts longer than at least the time required for one rotation of the transferring roller 18, the cleaning of the toner having the reverse polarity stack on the transferring roller 18 is completed.
