PROBLEM TO BE SOLVED: To provide a toner container that has an effect of easily distinguishing a genuine product from a fake product, and reliably preventing failure such as an image defect, without causing an increase in the number of components at a low cost.SOLUTION: A toner container of the present invention includes a container body provided with a filling port for filling toner, and a cap 29 that closes the filling port. The outer surface 67 of the cap 29 has a diffraction grating 68 formed thereon.

PROBLEM TO BE SOLVED: To prevent connection of a drive coupling and a driven coupling from being inadvertently released, while maintaining a simple configuration of a metal mold.SOLUTION: An image forming apparatus of the present invention includes a toner container, and an attachment member to which the toner container is attached. The toner container includes a container body provided with a discharge port, a rotating member provided rotatably to the container body, and a driven coupling 72 connected with the rotating member. The attachment member includes a drive coupling 126 connected with the driven coupling 72, and a driving source that rotates the drive coupling 126. A pressing part 136 provided to the drive coupling 126 presses a pressing target part 80 provided to the driven coupling 72, so that the drive coupling 126 and the driven coupling 72 rotate in the same rotation direction around the same rotation shaft A. The pressing target part 80 is arranged to approach the rotation shaft A from the upstream side in the rotation direction toward the downstream side.

PROBLEM TO BE SOLVED: To provide a toner replenishment device in which connection of a driving coupling and a driven coupling, and opening of a toner discharge outlet shutter and a toner supply inlet shutter can be simply performed without manual operation; and an image forming device including the same.SOLUTION: The toner replenishment device includes a toner cartridge 9 having a container body 9A, a toner discharge outlet shutter, and a driven coupling 25; a development device; a driving source for driving agitation and conveyance means of the toner cartridge 9; and a process frame 11 having a toner supply inlet port, a toner supply inlet shutter and a driving coupling 30. The driven coupling 25 is connected to the driving coupling 30 by interlocking with mounting of the toner cartridge 9. Further, the toner discharge outlet shutter and the toner supply inlet shutter are operated so that the toner discharge outlet port is communicated with the toner supply inlet port.

PROBLEM TO BE SOLVED: To securely fix a toner container to a mounting part and reduce the work load of an operator in attaching/detaching a toner container.SOLUTION: There is provided an image forming apparatus which comprises a toner container and a mounting part on which the toner container is detachably mounted. The toner container is provided with a lock piece 48. The mounting part is provided with a lock member 104. The lock member 104 comprises: an insertion recess 106 capable of inserting the lock piece 48 therein; a locking piece 110 movable between a protrusion position protruding to the insertion recess 106 and a retracted position retracted from the insertion recess 106 away from the protrusion position; and a biasing member 115 for biasing the locking piece 110 to the protrusion position side. If the locking piece 48 is inserted to a predetermined position in the insertion recess 106, the locking piece 110 presses the lock piece 48 to the back side in the mounting direction to the mounting part of the toner container by the biasing force of the biasing member 115.
