    摘要： A sealing structure includes a housing to accommodate powder, a powder roller having a surface to bear and convey the powder, and an entrance seal disposed between the powder roller and the housing to allow powder remaining on a circumferential surface of the powder roller to enter the housing. A pair of left and right edge seals is provided in a circumferential direction of the powder roller to overlap with outer circumferential surfaces of both ends of the entrance seal, respectively. Both ends of the entrance seal include powder damming sections extended from both ends thereof along the pair of left and right edge seals, respectively. A pair of inner edges of the respective powder damming sections is each sandwiched between a corresponding one of the pair of left and right edge seals and the powder roller while substantially symmetrically inclining from the rotation direction of the powder roller.

    摘要： The developer container includes a rotator that is rotated in the container body, a sequence of gears disposed outside the developer container that transmits a torque to the rotator, and a container guiding portion 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.

    摘要： A developer container includes a container body in which a developer containing chamber and a discharge outlet are formed, a developer conveyance member disposed inside the developer containing chamber and including a first conveyance portion and a second conveyance portion downstream from the first conveyance portion in a developer conveyance director, a canopy disposed inside the container body and facing the discharge outlet, a developer conveyance chamber defined by the canopy and an inner face of the container body in which the discharge outlet is formed, and a return opening formed in the canopy downstream from the discharge outlet. A developer conveyance velocity (Q2) of the second conveyance portion of the developer conveyance member to transports the developer toward the return opening is slower than a developer conveyance velocity (Q1) of the first conveyance portion of the developer conveyance member.
