    摘要： A developing device includes a developer bearer facing a latent image bearer, to rotate and supply developer to the latent image bearer, and a developer regulator to regulate an amount of the developer on a surface of the developer bearer. The developer regulator is in contact with the surface of the developer bearer. In the developing device, a ratio of a ten-point mean roughness of the developer regulator to a volume average particle diameter of the developer is not greater than 3.5%. The ratio is defined as Rzjis/Dv×100, where Rzjis represents the ten-point mean roughness measured in a nip-adjacent portion of a face of the developer regulator opposing the developer bearer, and Dv represents the volume average particle diameter of the developer. The nip-adjacent portion is adjacent to and downstream a downstream end of a regulation nip in a rotation direction of the developer bearer.

The sealing member has an end in a circumferential direction thereof to contact the surface of the rotator with a first pressure. The end in the circumferential direction is fixed to a bearing surface formed on the opening on at least one of an upstream side and a downstream side in a rotation direction of the rotator. The sealing member has an intermediate portion between an upstream end and a downstream end in the circumferential direction to contact the surface of the rotator with a second pressure lower than the first pressure.

    摘要： A charging device for applying a voltage to a latent image carrier of an image forming apparatus includes a brush roller, a voltage applying mechanism, and a driving mechanism. The brush roller includes a shaft and a brush. The brush has an oblique brush amount, and is disposed on an outer surface of the shaft while being disposed to a surface of the latent image carrier such that the brush roller is abutted with a brush contact amount. This brush is configured to uniformly charge the surface of the latent image carrier. The voltage applying mechanism is configured to apply a charging voltage to the brush roller. The driving mechanism is configured to drive the brush roller at a predetermined rotation number to satisfy a relationship Z>150−50 A, where Z is a rotation number (rpm) of the brush roller, and A is the oblique brush amount (mm).
