Abstract
A waste developer collecting device ejects and collects a waste developer used in a developing unit employing a two-component developing system in which a developer that contains toner and carrier is used. The waste developer collecting device includes: an opening and closing section for opening and closing a developer ejection opening formed on a bottom portion of the developing unit; an opening operation prohibiting section for prohibiting the opening operation of the opening and closing section; a collecting container for collecting the developer ejected through the developer ejection opening; and a collecting container fixing section for fixing the collecting container at a position where the developer ejected from the developing unit is collected. The opening operation prohibiting section allows the opening operation of the opening and closing section when the collecting container is coupled to the collecting container fixing section.
