A toner container detachably disposed in a body of an image forming device with a longitudinal direction of the toner container held in a horizontal direction, the toner container comprising: a cylindrical main part that is arranged to have an opening formed at one end in the longitudinal direction so that toner contained in the toner container is delivered to the opening; a cap part that accommodates the opening of the main part and includes a bottom formed into a toner outlet for discharging the toner from the opening of the main part downwards in a vertical direction to a part outside the toner container; and a shutter member that is held at the bottom of the cap part and arranged to open or close the toner outlet by movement of the shutter member along an outer circumferential surface of the cap part; wherein the cap part includes a non-compatible shape part disposed at a position on the outer circumferential surface of the cap part, the position being specific to a kind of the toner container to uniquely identify the kind of the toner container, the non-compatible shape part having a convex or concave shape, extending along the longitudinal direction and being arranged to confront from a position of a head end of the cap part in the longitudinal direction towards the main part; characterised in that the shutter member includes: a shutter main part (34d1) which opens and closes the toner outlet by engaging with a rail part provided in the cap part and moving along with the rail part; and a shutter deforming part (34d2) which is formed integrally with the shutter main part (34d1) to be elastically deformable in a vertical direction from a connecting location with the shutter main part (34d1); wherein the shutter deforming part (34d2) comprises: a stopper part (34d22) which regulates movement of the shutter member in a direction from a state in which the shutter member closes the toner outlet by contact with a contact part (34n5) formed in the cap part to a state in which the shutter member opens the toner outlet; and a stopper release part (34d21) which is formed to project downwards in the vertical direction and displaces the stopper part (34d22) upwards by elastic deformation of the shutter deforming part (34d2) to an upper part and cancels a contact state with the contact part (34n5) is provided by receiving an external force; wherein the stopper release part (34d21) is disposed to the non-compatible shape part on the side of the container main part in the longitudinal direction. a cylindrical main part that is arranged to have an opening formed at one end in the longitudinal direction so that toner contained in the toner container is delivered to the opening;
