To provide one form of a toner container and an image forming system.SOLUTION: A toner container has: a storage part that has a side face part forming a storage space for storing toner therein and extending in a first direction and a bottom face part closing a first end part side in the first direction of the storage space, and is formed of a flexible material; and a communication member that is connected with the side face part to close a second end part side in the first direction of the storage space, the communication member provided with a receiving port opening toward the storage space, a discharge port opening toward the outside of the toner container, and a channel communicating between the receiving port and the discharge port and in which the toner in the storage space flows toward the outside of the toner container, and the toner container is configured to discharge the toner in the storage space by deforming the storage part. A filling factor that is the ratio of the volume of toner filling the toner container to the capacity of the toner container including the storage space and a space inside the communication member communicating between the storage space and the discharge port is less than 0.63.SELECTED DRAWING: Figure 7
