A toner case includes a case main body, a rotating member, a transmitting member and a cover. The case main body contains a toner. The rotating member is disposed in the case main body and is rotatable around a rotation axis. The transmitting member rotates along an outer face of a side wall of the case main body on one side in a direction of the rotation axis so as to transmit a rotation to the rotating member. The cover covers at least a portion of the transmitting member. The transmitting member has a movable part which moves as the transmitting member rotates. The cover has a hole part through which the movable part is exposed.
