Claims

[Scope of Claim for Utility Model Registration] A developing unit that has a developing device containing a developer and is rotatably supported facing a latent image carrier, and a developer provided in the developing device. The conveying member is brought to the developing position by the rotation of the developing unit, and the developer conveying member brought to the developing position conveys the developer to the developing area between the member and the latent image carrier. A rotary developing device that visualizes an electrostatic latent image formed on a latent image carrier using a developer, and a sealing member for preventing scattering of the developer present in the developing area is attached to the developing unit, In a rotary developing device in which the sealing member is disposed in contact with the surface of the latent image carrier, the direction in which the amount of bending deformation of the sealing member due to external force received from the latent image carrier during rotation of the developing unit is reduced. The developing device as described above is characterized in that the direction of rotation of the developing unit is set so that the developing unit rotates only when the developing unit rotates.
