摘要： A developer supply device for supplying developer contained in a developer container toward a developing device in an apparatus body of an image forming apparatus includes a conveyance passage, a developer receiving portion, a sub-hopper, and a conveying tube. The conveyance passage delivers the developer discharged from the developer container. The developer receiving portion is detachable and attachable with respect to the developer container. The sub-hopper is detachable and attachable with respect to the developing device and stores the developer discharged toward the developing device. The flexible conveying tube has a first end portion coupled to the developer receiving portion and a second end portion coupled to the sub-hopper, and conveys the developer from the developer receiving portion to the sub-hopper. The developer supply device is detachable from and attachable to the apparatus body with a connection among the developer receiving portion, the sub-hopper, and the conveying tube being maintained.

摘要： A snap ring is set to a set portion of a shaft of a rotator from a direction orthogonal to an axial direction of the shaft. The snap ring includes a first arcuate portion and a second arcuate portion facing each other, being elastically deformable in directions away from each other, holding the set portion by elastic deformation restoring force. One ends of the first and second arcuate portions are away from each other to form an insertion portion to insert the set portion. When the snap ring is not used, the first arcuate portion has a same radius of curvature as the second arcuate portion and the set portion, and a center of curvature closer to the second arcuate portion than the first arcuate portion, and the second arcuate portion has a center of curvature closer to the first arcuate portion than the second arcuate portion.

摘要： A solid lubricant supply system includes a solid lubricant supplier to receive and supply solid lubricant to a solid lubricant supplying target. A pair of first and second moveable planar electrodes is opposed to each other. The second moveable planar electrode is partially moved toward the first moveable planar electrode as the solid lubricant is consumed. A residual solid lubricant quantity detecting unit is provide to detect a quantity of the residual solid lubricant at a first stage, in which the residual solid lubricant quantity is below a given level, by detecting electric conduction between the pair of first and second moveable planar electrodes when the pair of first and second moveable planar electrodes contacts each other. The first moveable planar electrode is enabled to further move together with the second moveable planar electrode when it is contacted and pressed by the second moveable planar electrode.
