Image forming apparatus provided with movable conveying unit

摘要

An image forming apparatus includes: a belt cleaning unit; a waste toner container; a conveying unit; and a support member. The cleaning unit collects waste toner adhered to a belt. The container stores the waste toner collected by the cleaning unit. The conveying unit conveys the waste toner from the cleaning unit to the container. The support member moves between an internal position inside the main casing and an external position outside the main casing. The support member in the internal position moves between a contact position where the photosensitive body contacts the belt and a separated position where the photosensitive body separates from the belt. The conveying unit moves along with the support member moving between the contact position and the separated position. The conveying unit is uncoupled from the container while the support member moves from the internal position to the external position.
