Abstract
A toner case includes a case main body, a cover, and a coil spring. The case main body is rotatable and has a toner containing space in which a toner is contained and an opening through which the toner is discharged from the toner containing space. The cover keeps a rotation stop state when the case main body rotates and has a communication space which communicates with the toner containing space via the opening. The coil spring is fixed to the cover so that at least a part of the coil spring is arranged in the communication space. The coil spring vibrates as the case main body rotates.
