Title: Image forming device
Inventor: HACHISUGA TOSHIJI
IPC: G03G15/06
Filed: 1999-02-05
Abstract: PROBLEM TO BE SOLVED: To prevent roughness and pitch irregularity by applying a DC voltage between an image carrier and a developer carrier and applying an AC voltage whose amplitude value continuously varies. SOLUTION: A bias voltage generation part 7 is composed of a DC voltage generation part 7a and AC voltage generation part 7b connected in series. In an AC voltage generated by the AC voltage generation part 7b, the amplitude of a rectangular wave repeated at 12 KHz varies continuously in a straight line at an interval of 1 KHz. A bias voltage is applied between a developing sleeve 1c and a photoreceptor drum 10 by the bias voltage generation part 7. When a positive AC voltage is applied, toner negatively charged in a magnetic brush does not move apart from carrier but remains sticking to the carrier. When a negative AC voltage is then applied thereto, the negatively charged toner moves apart from the carrier and proceeds to the photoreceptor drum 10. The toner is returned in the direction of the developing sleeve 1c by the following application of a positive AC voltage.  However, because the DC voltage has been applied, a distance covered by the return of it is not full.
