TONER SUPPLY MECHANISM, IMAGE FORMATION DEVICE AND TONER SUPPLY METHOD

摘要

PROBLEM TO BE SOLVED: To enable toner to be supplied to each color developing unit by a single motor without requiring a complicate mechanism such as a clutch mechanism and the like.SOLUTION: A toner supply mechanism 50 comprises: a plurality of toner containers 17M to 17Bk that includes a shutter mechanism 171 performing an open/close operation by being pressed, and supplies toner of each stored color to each of developing units 12M to 12Bk by the shutter mechanism being opened; a shaft 61 in which a plurality of cams 62M to 62Bk each abutting on the shutter mechanism 171 of the plurality of toner containers 17M to 17Bk is disposed at a location different in a shaft direction and shaft periphery; a stepping motor 60 that rotates to drive the shaft 61; and a motor control unit 101 that controls a rotation action of the stepping motor 60.
