TONER CARTRIDGE

The developer container (50) includes a rotator (53) that is rotated in the container body, a sequence of gears (62, 63, 64) disposed outside the developer container that transmits a torque to the rotator, and a container guiding portion (73a) that fits with a main body side guiding portion and guides the developer container in a direction in which the developer container is attached to a mounting portion of an image forming device main body. A first gear included in the sequence of the gears is movable between an operating position where the first gear engages with a second gear and a retracted position where the first gear is retracted. On a surface on which the container guiding portion is disposed, a part of the container guiding portion is disposed within a projected area of the first gear being disposed at the operating position.
