    摘要: The developing device includes a developer bearer, a conveyor, a casing including a ceiling, and a seal. The developer bearer is configured to bear a developer and develop a latent image. The conveyor is configured to convey and stir the developer. The casing is configured to contain the developer, the developer bearer, and the conveyor. The seal is configured to seal the inside of the casing to form a closed space that encloses the developer in the developing device. The conveyor is configured to be partially or entirely buried in the developer enclosed in the closed space in both of a normal posture and an upside-down posture of the developing device. A cross-sectional area of the closed space in a horizontal plane gradually increases from a top of the ceiling of the casing toward a bottom of the developing device in the normal posture of the developing device.

    摘要: A development device includes a developer bearer to carry by rotation developer to a development range facing a latent image bearer and a developer regulator to adjust an amount of developer transported to the development range by the developer bearer. The developer bearer includes a developer carrying range having surface unevenness; and a surface of the developer bearer is coated with a coating material including a resin material and particles to roughen the surface.
