A drive transmission structure includes a driven shaft, a drive shaft, and a bearing member. The driven shaft has a drive receiving gear attached thereto and a first shaft portion near the drive receiving gear, to which a rotational force is transmitted. The drive shaft has a drive transmitting gear attached thereto and a second shaft portion near the drive transmitting gear. The drive transmitting gear is engaged with the drive receiving gear so as to transmit the rotational force. The bearing member has a first bearing and a second bearing, which respectively support the first shaft portion and the second shaft portion. In the drive transmission structure, the axis of the drive shaft does not intersect and is non-parallel to the axis of the driven shaft, and the first and second bearings are integrally formed with the bearing member.

A developer transporting device includes a transporting device body having an inlet, an inlet cover member that opens and closes the inlet, a container having an outlet, an outlet cover member that opens and closes the outlet, a restraining member that restrains an opening movement of the inlet cover member, and a releasing member that is capable of releasing the inlet cover member from the state in which the opening movement is restrained. The restraining member restrains the opening movement of the inlet cover member when the outlet cover member is closed. The releasing member releases the inlet cover member from the state in which the opening movement is restrained when the outlet cover member is open.

An image forming apparatus includes a detachable-body mounted member, a detachable body and a sealing portion. The detachable-body mounted member includes a first opening and a first opening-and-closing member that opens and closes the first opening. The detachable body includes a second opening and a second opening-and-closing member. When the detachable body is attached, the second opening allows developer to flow into the first opening. The second opening-and-closing member opens and closes the second opening. When the detachable body is being attached or detached, the sealing portion seals a gap between (i) a front end face of the second opening forming member and (ii) a rear end face of the first opening-and-closing member.
