CONTROLLING DEVICE FOR SUPPLY TONER IN AN IMAGE FORMING APPARATUS

摘要

PURPOSE: A toner feed adjusting apparatus for a video formation device is provided to always feed necessary quantity of a toner to a supply roller by selectively controlling a rotation of an agitator of a toner accommodating unit which feeds the toner to the supply roller. CONSTITUTION: A photosensitive drum(1) is installed in a housing(2). An electrification roller(3) is mounted on the surface of the photosensitive drum(1). An exposure unit(4) which exposures a regular video is formed on one side of the photosensitive drum(1). A developer roller(6) is mounted on one side of the photosensitive drum(1) in order to attach a toner(5) to the part in which a latent electrostatic image is formed by the exposure unit(4) of the photosensitive drum(1). A blade(7) is mounted and fixed in the housing(2). A supply roller(8) is installed on the other side of the developer roller(6). An agitator(9) which agitates the toner(5) is installed on one side of the supply roller(8). The supply roller(8) and the agitator(9) are installed in a toner accommodating part(10) inside of the housing(2).
