Abstract

A scattering toner (sometimes called toner cloud) is one of the big problems in a two-component development system, especially in the color imaging system. The scattering toner phenomena are analyzed by microscopic visuali-zation technique and interactions with airflow caused by the magnetic carrier brush are clarified. The boundary area between color developer and photoconductor (nip area) are observed using a high-speed camera with a microscopic lens. A special sucking airflow is generated at the edge of developer case and the scattering toner phenomena in the nip area are restrained by this airflow. The decreasing pressure in the developer case is resulted from the movement of the magnetic carrier brush on the surface of the developer sleeve. As the result two contrary airflows exist close to each other. One is the airflow on the surface of the sleeve produced by rotating roller and the other is by the movement of the magnetic carrier brush. In addition, the stronger is the sprinkling movement of the magnetic carrier brush, the more scattering toner phenomena are observed.
