現像装置。[Scope of Claim for Utility Model Registration] In a developing device that develops an electrostatic latent image formed on a latent image carrier with a developer carried on a developer carrying member, during development, a developing device that develops an electrostatic latent image on the developer carrying member A second position is placed at a first position where the developer is supplied to the developer, and a second position is located at which the developer is not supplied to the developer carrying member during non-development.
a displacement member that is placed at a first position and can be freely displaced between the two positions; and in conjunction with the displacement operation of the displacement member, when the displacement member is displaced to a first position, the developer on the developer carrying member is hidden. When the displacement member is displaced to a contact position with the latent image carrier, which closes off the wedge-shaped space on the side facing the image carrier from the outside, and the displacement member is displaced to the second position, the member is separated from the latent image carrier. 1. A developing device comprising: a sealing member that can be moved to a position where the developing device is
