Claim:
An image forming device comprising: an image forming device main body; an image bearing member rotatably mounted on the image forming device main body; a development device configured to supply toner to a surface of the image bearing member; a plurality of toner holding containers mounted in juxtaposition on the image forming device main body, each toner holding container comprising a toner holding container main body, a toner transport member rotatably mounted within the toner holding container main body and configured to transport the toner; and a drive power transmission mechanism comprising a housing mounted on the image forming device main body, a shaft member mounted on the housing so as to be axially rotatable and movable in the axial direction, a first transmission mechanism mounted on the housing and configured to transmit a drive power of a drive means to the shaft member so that the shaft member moves in the axial direction, and a second transmission mechanism mounted on the housing configured to transmit the drive power of the drive means to the shaft member so that the shaft member is rotated, and the toner transport member that is to be driven being rotated by moving the shaft member in the axial direction with the drive power that is transmitted to the shaft member by the first transmission mechanism, and rotating the shaft member with the drive power that is transmitted to the shaft member by the second transmission mechanism.
