Filed: 1994-09-02
Abstract: PURPOSE: To simplify a member for disturbing the transfer remainder by applying the voltage to the blush capable of discharging between a photoreceptor, and disturbing the transfer residual toner whose sum total of the electric charge becomes near to zero. CONSTITUTION: When the transfer residual toner on the photoreceptor drum 1 reaches the vicinity of the disturbing blush 71 after transferring by the transfer device 5, the electric discharge is generated by the voltage from the disturbing power source 73, between the non-contact part of the disturbing blush 71 composed of the rayon containing the carbon and the organic photosensing layer of the photoreceptor 1. The negative electric charge is injected to the transfer residual toner by this electric discharge, the sum total of the electric charge of the positively electrified transfer residual toner approximately becomes zero, and thus the transfer residual toner becomes free from the attraction by the photoreceptor drum 1. Then, the toner is disturbed on the surface of the photoreceptor drum 1 by the contact part of the disturbing blush 71 and positively electrified again by the electrifying device 2. As a result, the transfer residual toner can be disturbed by only one member, hence the image forming device can be lightened and miniaturized.
