Patent JP-S6314175-A (JP)
Title: Image forming device
Inventor: YOSHIKAWA MASAO
IPC: G03G15/01
Filed: 1986-07-07
Abstract: PURPOSE:To form a sharp multicolor copy image without color mixing by employing two-component magnetic brush development and making the volume of magnetic particles at a development part small enough to open the surface of a developer carrier. CONSTITUTION:An electrostatic latent image consists of negative charges, but an image part is exposed, so an area 11a where there is no charge is developed with toner 21 which is charged electrostatically to the negative polarity. Then, the image is charged again by a charger 12 to the same potential with the no-image area. A magnetic brush 23 develops an image area 11a, but is napped in a rough state, so the surface of a sleeve 6c is exposed and the toner 21 leaves both the surface of the sleeve 6c and the surface of the magnetic brush 23 to perform development and never perform the development in other areas; and the magnetic brush 23 is in the rough state, so the image is neither disordered nor scraped off even when the brush contacts the 1st developed image.
