摘要： A developing device includes a developing container, a toner carrier, and a plurality of air outlet ports. The plurality of air outlet ports are formed in such part of a wall of the developing container as faces the toner carrier, along a longitudinal direction of the developing container, the air outlet ports communicating with a duct next to the developing container. The toner carrier includes a coat layer on the outer circumferential surface thereof. The coat layer is formed by dripping the toner carrier into a resin coating liquid with one end in the longitudinal direction thereof first, the one end being a lower end of during the dipping, and then lifting the toner carrier out of the resin coating liquid. The toner carrier is arranged such that the lower end of during the dipping is disposed on an upstream side with respect to an airflow direction in the duct.

摘要： In a developing device, a developing coating layer of each of a plurality of developing rollers has been formed by a dipping method in which a developing base body is dipped in a liquid in a state where the developing base body is in a vertical attitude such that a first end of the developing base body faces down and a second end of the developing base body faces up. The plurality of developing rollers are arranged from an upstream side to a downstream side in a rotation direction of an image-carrying member in such a manner that directions faced by the first end and the second end of each of the plurality of developing rollers are alternately reversed.

摘要： A developing device includes a storing portion, a stirring member, a developing roller, a shield plate, and a guide portion. The storing portion stores developer. The stirring member is rotatably provided in the storing portion and stirs the developer in the storing portion by being rotationally driven in a predetermined first rotation direction. The developing roller is rotatably provided above the stirring member, has a magnet that attracts the developer in the storing portion by a magnetic force, and is rotationally driven in a predetermined second rotation direction. The shield plate is made of a nonmagnetic material and provided at a facing position where the developing roller and the stirring member face each other. The guide portion is provided more on an upstream side in the first rotation direction than the facing position, and guides the developer from the storing portion to the developing roller side.

摘要： A developing device includes a housing, a developer carrier, a conveying member and a surface layer. The developer carrier carries a developer on a circumferential surface. The conveying member is rotatably arranged in a first conveying portion and conveys the developer in the first conveying direction and supplies the developer to the developer carrier. The surface layer is formed on a surface of a predetermined cylindrical base member. The surface layer is formed by an immersion method of immersing the base member in a predetermined immersion tank so that an axial direction of the base member extends along a vertical direction. A lower end side of the base member at the time of the immersion is arranged in an upstream side of the housing and an upper end side of the base member at the time of the immersion is arranged in a downstream side of the housing.
