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.
