Powder bin structure sealed by magnetic piece

The utility model discloses a powder bin structure sealed by magnetic parts, which comprises a powder bin, magnetic sealing parts attached to a magnetic roller are arranged on the powder bin on the left side and the right side of a powder outlet of the powder bin, and the surfaces, facing the magnetic roller, of the magnetic sealing parts are arc-shaped surfaces. When the magnetic sealing element is used as a sealing element, carbon powder can leak between the magnetic sealing element and the magnetic roller, and the carbon powder is left between the magnetic sealing element and the magnetic roller under the action of magnetic attraction, so that not only can the problem of carbon powder leakage be solved, but also the space for powder leakage can be closed by blocking the leaked carbon powder between the magnetic sealing element and the magnetic roller. The problem that the existing felt cannot solve the problem of powder leakage after gaps exist is solved. Meanwhile, through the principle of homopolar repul
