    摘要： A develop unit is configured to include a developer roller having a developer sleeve and a magnetic roller with a magnetic pole, a supply path formed in parallel with an axial direction of the developer roller, a supply screw supplying the developer to the developer roller, and a first bulkhead forming the supply path. In the developer unit, the magnetic pole is disposed so that a normal line through a maximum magnetic flux density point in a circumferential direction coincides with a tangent line to an upper portion of the supply screw in a rotary direction, the maximum magnetic flux density point being a point at which a density of a magnetic flux from the magnetic pole is maximum on an outer surface of the developer sleeve.

    摘要： A magnetic particle carrying device includes a magnetic field generator and a hollow cylindrical structure. The magnetic field generator generates a magnetic field. The hollow cylindrical structure encases the magnetic field generator and attracts magnetic particles on an external surface of the hollow structure using the magnetic field. The external surface of the hollow cylindrical structure is provided with a plurality of elliptical depressions. The depressions include first type depressions and second type depressions. A long axis of a first type of elliptical depression is substantially extending in an axial direction of the hollow cylindrical structure, and a long axis of a second type of elliptical depression is substantially extending in a circumferential direction of the hollow cylindrical structure. The external surface of the hollow cylindrical structure has more elliptical depressions of the second type than elliptical depressions of the first type.
