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.

An image forming apparatus includes a main frame, a plurality of process cartridges, a cartridge-supporting body, a belt, a belt cleaning unit, a waste toner cartridge, and a collective conveying unit. Each drum-cleaning unit collects waste toner on a corresponding photosensitive drum. The cartridge-supporting body supports the process cartridges and is movable between an internal position inside the main frame and an external position outside of the main frame. The belt cleaning unit collects waste toner on the belt. The waste toner cartridge accommodates both waste toner collected from the photosensitive drums by the drum-cleaning units and waste toner collected from the belt by the belt cleaning unit. The collective conveying unit aggregates both waste toner collected from the photosensitive drums by the drum-cleaning units and waste toner collected from the belt by the belt cleaning unit and conveys the aggregated waste toner to the waste toner cartridge.

An image forming apparatus includes a main frame, a plurality of process cartridges, a cartridge-supporting body, a belt, a waste toner cartridge, a contact-separation mechanism, and a collective conveying unit. Each process cartridge includes a photosensitive drum and a drum cleaning unit collecting waste toner on the drum. The cartridge-supporting body is movable between an internal position inside the frame and an external position outside the frame. The belt confronts the process cartridges in the internal position. The waste toner cartridge accommodates the waste toner collected from the drums. The contact-separation mechanism moves the cartridge-supporting body between a contact position where the drums are in contact with the belt and a separated position where the drums are out of contact with the belt. The collective conveying unit aggregates waste toner collected from drums and conveys collectively the aggregated waste toner to the waste toner cartridge.

A fixation unit includes a fixation member and a housing containing therein the fixation member. The fixation member is configured to thermally fix a developer image onto a medium being conveyed from an image formation unit to the fixation unit along a medium conveyance path, wherein the developer image is formed at the image formation unit and transferred onto the medium by the image formation unit. The developer attachment member is replaceably provided to the fixation unit and configured to attach thereto a part of the developer that is scattered in the neighborhood of the conveyance path.
