A toner container includes: a containing unit that contains a toner; a storage device that stores information; and an attachment unit. The attachment unit includes a cover member, a supporting member, and an insertion member. The cover member has a first projection and an insertion opening. The first projection extends in a first direction. The insertion opening is provided on the first projection and extends in a second direction. The supporting member has a first depression and a through opening. The first depression extends in the first direction and allows the first projection to be inserted into the first depression. The through opening extends in the second direction and is in communication with the first depression. The insertion member is inserted into the through opening and the insertion opening in a state where the storage device is positioned between the cover member and the supporting member.

A toner container installed in an image forming apparatus includes a toner container main body having a predetermined length and in which toner is accommodated, a discharge port through which the toner is discharged from the toner container main body, a shutter which opens and closes the discharge port, a handle provided on the toner container main body, and a pressed portion provided on the toner container main body and which is pressed by the image forming apparatus to project the handle out from the image forming apparatus.

A toner container is elongated. A first rotating member is rotatably provided in a first toner storage portion and extends in a depth direction of a container main body. A first drive input portion is provided at an end of a first rotation shaft included in the first rotating member and configured to receive a driving force. A second rotating member rotatably provided in a second toner storage portion and extends in the depth direction. A second drive input portion is provided at an end of a second rotation shaft included in the second rotating member and configured to receive a driving force. The container main body includes a plate-like coupling member coupling a first housing of the first toner storage portion with a second housing of the second toner storage portion.

An image forming apparatus includes a cartridge storage portion that is installed in an image forming apparatus main body, and a toner cartridge that is configured so as to be able to be inserted into and removed from the cartridge storage portion. The cartridge storage portion has a storage opening that receives the toner cartridge, and has a gap between an end part of the toner cartridge and the storage opening, through which the end part of the toner cartridge is not able to be held, when the toner cartridge is stored in the cartridge storage portion.

A toner container for use in an image forming device according to one example embodiment includes a body having a reservoir for holding toner. The toner container includes an electrical connector having an electrical contact for contacting a corresponding electrical contact in the image forming device when the toner container is installed in the image forming device. The electrical connector is positioned in one of a plurality of predetermined positions relative to the body corresponding to at least one of a toner color and a toner type of the toner container for limiting installation of the toner container to one of a plurality of toner container receptacles in the image forming device corresponding to at least one of the toner color and the toner type of the toner container.

A toner container includes a container body, a cap, bosses and a cover. The container body has a toner filling port. The cap is detachable and closes the filling port. The bosses are provided on the container body. The cover is detachably attached to the container body so as to cover the filling port and the bosses, and has a through hole through which each of the bosses penetrates. The boss has a tip end portion protruding from the cover through the through-hole. The tip end portion is provided so as to regulate detachment of the cover by being worked into a head portion having a cross-sectional area larger than the through-hole, and to permit the detachment of the cover by cutting off the head portion. The container body, the cap and the cover can be reused maximum by the number of times corresponding to the number of the bosses.

A toner container installed in an image forming apparatus includes a toner container main body having a predetermined length and in which toner is accommodated, a discharge port through which the toner is discharged from the toner container main body, a shutter which opens and closes the discharge port, a handle provided on the toner container main body, and a pressed portion provided on the toner container main body and which is pressed by the image forming apparatus to project the handle out from the image forming apparatus.
