Image reproduction apparatus including a waste toner assembly

An image reproduction apparatus comprising:

• an image formation part which is provided inside a main body and detachably attached to the main body;
• a waste toner assembly which is movable from a closed position to an open position to allow for the detachment of the image formation part from the main body, and comprises a transport part transporting a waste toner generated by the image formation part to a waste toner bottle;
• a retainer which is movable from a closed position to an open position to allow for detachment of the image formation part, and holds the image formation part;
• a first locking part associated with the waste toner assembly which is provided at the waste toner assembly and latches the waste toner assembly to the main body;
• a second locking part associated with the retainer which is provided at the retainer and latches the retainer to the main body;
• and
• a release lever which is rotatable and provided at the waste toner assembly, wherein
• when the release lever is repositioned, the first locking part of the waste toner assembly, and the second locking part of the retainer are simultaneously unlatched;
• and wherein the first locking part of the waste toner assembly and the second locking part of the retainer are released by a rotation of the release lever;
• and
• a locking timing adjusting part which comprises,
• a first transmission part transmitting to the first locking part of the waste toner assembly, a power generated by a rotation of the release lever;
• and
• a second transmission part transmitting to the second locking part of the retainer, a power generated by a rotation of the release lever, wherein
• the first transmission part is distanced from the second transmission part.

• wherein the transport part comprises a transport pipe and a screw conveyer comprising a spiral blade rotated and driven around an axis of the spiral blade inside the transport pipe, and
• the waste toner bottle is attached below the transport pipe;
• and
• wherein
• the transport pipe extends approximately in a horizontal direction inside of the waste toner assembly, and
• the waste toner assembly is provided so that the waste toner assembly rotates in an upper and lower direction around a supporting axis which is provided at a lower end of the waste toner assembly, the supporting axis being parallel to an axis of the transport pipe and being provided below the axis of the transport pipe by a predetermined distance.
