A toner container includes: a container that accommodates toner and transports, by rotating, the toner to an opening disposed at a first end portion in a direction of a rotation axis; a support portion that covers a periphery of the container near the first end portion, and supports the container to be rotatable in a circumferential direction, the support portion being attached to an image forming apparatus body and having a sealant interposed between the support portion and the container; and a fixing portion that fixes the container and the support portion to each other while the sealant is compressed when the support portion is rotated relative to the container in a first circumferential direction.
