摘要： An image forming apparatus includes image bearers, developing devices, developer containers, and developer supply devices. The image bearers are arranged side by side along a movement direction of an intermediate transferor or a sheet. The developing devices, the developer containers, and the developer supply devices are configured to be rearrangeable for each color in the movement direction in a manner that one or each of a developing device, a developer container, and a developer supply device corresponding to each color of the different colors is detached from and attached to the image forming apparatus, separately from a rest of the developing device, the developer container, and the developer supply device. The image forming apparatus is configured to be available for use when colors of the developing device, the developer container, and the developer supply device correspond to each other after rearrangement.

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.
