  • Electro-photographic image forming apparatus having a function for preventing toner for scattering and control method for the same
    Patent number: 7058334
    Abstract: An electro-photographic image forming apparatus preventing toner from scattering during a printing operation and a control method of the same. The electro-photographic image forming apparatus includes a scattering preventive member being disposed downstream of the developing roller at a predetermined distance from the photosensitive medium, and a voltage being applied, and a controller controlling the voltage that is applied to the scattering preventive member so as to transport the toner attached on the scattering preventive member to the photosensitive medium.
    Type: Grant

  • Developing device having a developer scatter prevention unit and an electrophotographic image forming apparatus using the same
    Patent number: 7046940
    Abstract: A developer scattering prevention unit used with an electrophotographic image forming device includes an air inlet/outlet pipe installed adjacent to an intermediate area between an image carrier and a developer and having a first air inlet/outlet port opened toward the intermediate area, and at least one vacuum source installed on at least one of the image carrier and the developer carrier to communicate with the air inlet/outlet pipe to control air to flow from the intermediate area through the first air inlet/outlet port. A developing device having this developer scattering prevention function becomes simplified in structure.
