摘要： A developing device includes two developer-transporting members, a container, and four gap retainers. The container contains a developer and rotatably supports rotation shafts of the developer-transporting members using side walls located on both end portions. The gap retainers are supported at end portions of the developer-transporting members and are brought into contact with a subjected-to-development member or a supporter to maintain a gap between the subjected-to-development member and each developer-transporting member. A force with which the two developer-transporting members are pressed toward the subjected-to-development member is applied to the container and all the gap retainers are brought into contact with the subjected-to-development member or the supporter, while axes of rotation of the two developer-transporting members are allowed to become non-parallel with an axis of rotation of the subjected-to-development member.

摘要： A developing device includes a developer transport body that transports developer to develop an electrostatic latent image on an image carrier, a housing that holds the developer transport body and defines an exposed portion and an unexposed portion, the housing including a storage portion storing the developer, and a layer-thickness regulation member that regulates a layer thickness of the developer transported to the exposed portion and includes one side close to a surface of the developer transport body, a first portion, and a second portion. The housing includes first faces that define both ends of the storage portion in the rotation axis direction of the developer transport body, a second face, and a third face. The developing device further includes a closing member that closes a gap between the layer-thickness regulation member and the second and third faces, and a magnet provided between the second and third faces.
