| 发明名称 | Support member, image carrier, and image forming apparatus | ||
| 摘要 | A support member supported in a cylinder included in an image carrier includes a separation-space-defining portion that is arranged at a certain position in a circumferential direction and extends in an axial direction of the cylinder so that the support member has an arc shape; and a groove-defining portion that extends in the axial direction. An outer diameter of the support member in a central region in the axial direction is smaller than an outer diameter of the support member at both ends in the axial direction. In a state in which the support member is supported in the cylinder, the groove-defining portion is elastically deformed such that elastic restoring force generated in the central region is greater than elastic restoring force generated at the ends. | ||

| 主权项 | 1. A support member supported in a cylinder included in an image carrier, the support member comprising: a separation-space-defining portion that is arranged at a certain position in a circumferential direction and extends in an axial direction of the cylinder so that the support member has an arc shape; and a groove-defining portion that extends in the axial direction, wherein an outer diameter of the support member in a central region in the axial direction is smaller than an outer diameter of the support member at both ends in the axial direction, and wherein, in a state in which the support member is supported in the cylinder, the groove-defining portion is elastically deformed such that elastic restoring force generated in the central region is greater than elastic restoring force generated at the ends. | ||
