AbstractA developer-remaining-amount notifying device for notifying a remaining amount of a developer accommodated in a developer accommodating unit and used for developing a latent image formed on an electrophotographic photosensitive member is provided. The device includes a position detection member positionable near an upper surface of an accumulated layer of the developer accommodated in the developer accommodating unit, a regulating member, and a notification device. The regulating member regulates a moving direction of the position detection member such that the position detection member moves substantially linearly in accordance with a gradual decrease of the developer accommodated in the developer accommodating unit as the developer is used for development. The notification device notifies a remaining amount of the developer accommodated in the developer accommodating unit in accordance with a position of the position detection member.
