发明名称 Developer Supply Device
摘要 A developer can be appropriately carried by a brush roller in a developer supply device in which the brush roller is used as a developer carrying member. A developer carrying amount regulating member is positioned such that a tip portion of the developer carrying amount regulating member that is positioned close to a developer carrying member is inserted into a brush layer. The tip portion includes a surface positioned at an upstream side in a moving direction of the brush layer. The surface faces fibrous members that move to the developer carrying amount regulating member in the moving direction. The surface is configured to be inclined in the same direction as the moving direction.

主权项 1. A developer supply device configured to supply a powdery developer to a supply target, comprising: a developer accommodation section for accommodating the developer therein; a developer carrying member comprising a roller body and a brush layer, the roller body having a cylindrical shape with an outer peripheral surface, the roller body being configured to be rotatable, the brush layer having a plurality of flexible fibrous members planted on the outer peripheral surface, and the brush layer being configured to carry the developer supplied from the developer accommodation section; and a developer carrying amount regulating member configured to contact with the brush layer at a position which is upstream of a region where the brush layer faces the supply target in a moving direction of the fibrous members by rotation of the developer carrying member, the position being downstream of a region where the developer is supplied from the developer accommodating section to the brush layer in the moving direction to thus regulate an amount of the developer carried by the brush layer, wherein the developer carrying amount regulating member comprises a tip portion positioned at the developer carrying member and configured to be inserted in the brush layer, and the tip portion having a surface positioned at an upstream side in the moving direction, and the surface faces the fibrous members that move in the moving direction to the developer carrying amount regulating member, and the surface is configured to be inclined in a direction the same as the moving direction.
