Image forming apparatus having a developer collecting duct

摘要

An image forming apparatus includes: a developer collecting duct that is linear and has a plurality of coupling portions vertically spaced apart from each other; and a plurality of developer discharging sections that each have an engaging portion inserted into one of the coupling portions to thereby be disposed as being exposed to the inside of the developer collecting duct, and that discharge waste developer to the developer collecting duct through a developer outlet provided in the engaging portion. Second and subsequent ones of the developer discharging sections from the top are detachably attached to the developer collecting duct. The developer collecting duct has a flow path restricting portion that restricts the area through which the waste developer flows down to prevent the waste developer from hitting the engaging portion of lower one of the developer discharging sections.

1. An image forming apparatus comprising:
a developer collecting duct that is linear and has a plurality of coupling portions vertically spaced apart from each other; and a plurality of developer discharging sections that each have an engaging portion inserted into one of the coupling portions to thereby be disposed as being exposed to the inside of the developer collecting duct, and that discharge waste developer to the developer collecting duct through a developer outlet provided in the engaging portion, wherein second and subsequent ones of the developer discharging sections from the top are detachably attached to the developer collecting duct, and the developer collecting duct has a main flow path that each of the developer outlets face, and through which the waste developer flows down, and a sloped portion or a hood portion that guides the waste developer to the main flow path and prevents the waste developer from hitting the engaging portion of a lower one of the developer discharging sections.
