摘要： A developing device is provided. The developing device includes a developer carrier, a regulator, a first developer storing chamber, a plurality of conveyers disposed within the first developer storing chamber, a second developer storing chamber in communication with the first developer storing chamber, and a supply member disposed within the second developer storing chamber. The developer carrier carries developer on its surface and supplies developer to a latent image carrier carrying a latent image. The regulator regulates the thickness of developer on the surface of the developer carrier. The first developer storing chamber stores developer separated from the developer carrier by the regulator and is to be supplied with fresh developer. Each of the plurality of conveyers coveys developer in a different conveyance direction. The second developer storing chamber is to be supplied with developer from the first developer storing chamber. The supply member supplies developer to the developer carrier.

摘要： A developing device includes a toner bearer including a surface in which multiple recesses having a cross-sectional void rate of 50% or smaller are formed, a toner supply member to supply toner to the toner bearer, and a developer regulator disposed facing or in contact with the toner bearer and including a bent tip portion. The toner bearer has a surface roughness Ra within a range from 1.0 μm to 2.0 μm, and a surface area ratio within a range from 2.0 to 4.0. The developing device uses polymerized toner having a weight average particle diameter of 8.0 μm or smaller and an average circularity of 0.98 or greater.

摘要： A sealing assembly to contact a rotator includes a sealing member to slidably contact a surface of an end of the rotator in an axial direction of the rotator. 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.
