Abstract
The waste toner container includes: a waste toner detection unit configured to detect a state in which a toner surface of waste toner at that position is displaced up to a ceiling portion or near the ceiling portion. The waste toner detection unit includes: a flexibility member installed so as to cover an opening portion formed in the ceiling portion or a side wall and is configured to be deformed by a direct or indirect push by the waste toner; and a movable member formed so as to contact the flexibility member from outside of the container and so as to be displaced by the direct or indirect push by the waste toner interposing the flexibility member such that displacement thereof is detected by a detection unit. The displacement of the movable member is limited by a regulating member.
