PROBLEM TO BE SOLVED: To realize simple constitution where the kind of liquid with which developer is replenished is unified by providing the device with plural rollers including a developing roller developing an electrostatic latent image to a developed image and providing the plural rollers with a tank individually and respectively. SOLUTION: A developing roller tank(DR tank) 6 having the developing roller(DR) 5 developing the latent image on a photoreceptor drum 1, a scooping roller tank(RR tank) 6 having a scooping roller(RR) 7 scooping the developer on the drum 1, and an SR tank 10 having a set roller(SR) 9 binding toner in the developer by the electric field are arranged in the device. In a developing stage, the developer CT sticking to the DR 5 after passing through a developing area is scraped by a DR scraper 5a and restored to the DR tank 6 again. After development, the developer CT remaining on the drum 1 is scraped by an RR scraper 7a by the rotation of the RR 7 and recovered in the RR tank, then the developer is unified. |
