发明名称 DEVELOPING DEVICE
摘要 PURPOSE:To eliminate the need of keeping a gap for allowing electrified toner to fly up to the electrostatic latent image of an electrostatic latent image carrier with high accuracy, to easily stick the electrified toner to an electrostatic latent image part and to form a stable toner image by scraping/supplying the electrified toner onto the electrostatic latent image carrier and sticking the electrified toner to the electrostatic latent image of the electrostatic latent image carrier with electrostatic force. CONSTITUTION:Toner dropped/supplied from a toner replenishing container 9 is rubbed with an electrifying brush 1, a friction member 27 and a carrying roller 2 and charged by the friction. The electrified toner 13 is electrically stuck to the carrying roller 2 and carried up to a supplying position on the electrostatic latent image carrier 12. The stuck electrified toner forms a toner layer having a constant thickness in the iongitudinal direction of the carrying roller 2, in such a manner that a regulating plate 17 is arranged without contact with the carrying roller 2. A scraping brush 3 is disposed at a place where the electrified toner 13 arrives, so that the electrified toner 13 stuck to the carrying roller 2 is scrapped and then, stuck to the electrostatic latent image of the electrostatic latent image 12, to form the toner image.
