1. A rotary device comprising: a rotary shaft;a rotary body that is supported by the rotary shaft, and rotates about the rotary shaft; andat least one plate-like member having a central point that serves as a center of rotation when the plate-like member rotates, the plate-like member having an outer peripheral portion, the plate-like member including at least one cutout formed by cutting out the outer peripheral portion of the plate-like member at positions that are symmetric with respect to a straight line passing through the central point, the plate-like member being secured to the rotary shaft to rotate together with the rotary body as the rotary shaft rotates, whereinthe at least one plate-like member comprises a plurality of plate-like members, the plate-like members being all identical in dimensions and shape and stacked together with the respective cutouts of the plate-like members aligned with each other. 2. An image forming apparatus comprising: a main body;a consumable item that is consumed as an image is formed, the consumable item being inserted into or removed from the main body of the image forming apparatus; andan endless member having an outer peripheral surface, the endless member being stretched under tension between a plurality of rollers including a rotary device to transport a toner image while holding the toner image on the outer peripheral surface, the rotary device comprising a rotary shaft,a rotary body that is supported by the rotary shaft, and rotates about the rotary shaft, andat least one plate-like member having a central point that serves as a center of rotation when the plate-like member rotates, the plate-like member having an outer peripheral portion, the plate-like member including at least one cutout formed by cutting out the outer peripheral portion of the plate-like member at positions that are symmetric with respect to a straight line passing through the central point, the plate-like member being secured to the rotary shaft to rotate together with the rotary body as the rotary shaft rotates, whereinthe at least one cutout comprises a plurality of cutouts, and when the consumable item is to be inserted or removed in a direction that crosses a direction of transport of the endless member, the consumable item is inserted or removed by passing the consumable item through one of the cutouts. 3. The image forming apparatus according to claim 2, wherein the consumable item comprises a process unit including an image carrier that carries the toner image. 4. An image forming apparatus comprising: a main body;a consumable item that is consumed as an image is formed, the consumable item being inserted into or removed from the main body of the image forming apparatus; andan endless member having an outer peripheral surface, the endless member being stretched under tension between a plurality of rollers including the rotary device according to claim 2 to transport a toner image while holding the toner image on the outer peripheral surface,wherein the at least one cutout comprises a plurality of cutouts, and when the consumable item is to be inserted or removed in a direction that crosses a direction of transport of the endless member, the consumable item is inserted or removed by passing the consumable item through one of the cutouts.
