Toner supply container and image forming apparatus |
摘要 |
A toner supply container has a container body and a conveyance member rotatably arranged inside the container body and which conveys toner toward a discharge opening of the container body when driven to rotate by external force. The conveyance member includes a cylindrical rotary body and a screw blade member wound around the cylindrical rotary body so that the screw blade member stands on an outer circumferential surface of the cylindrical rotary body. The inner surface of a bottom wall of the container body includes a cylindrically curved surface identical to a part of a circumferential surface of an imaginary cylinder whose axis is substantially the same as a rotation axis of the conveyance member. A curvature radius of the cylindrically curved surface is set so the conveyance member rotates in a state where an outer circumferential edge of the screw blade member substantially slides on the cylindrically curved surface. |
