Abstract:
1. A sealing assembly to contact a rotator, the rotator disposed in an opening in a direction traversing the opening to convey powder held on a surface of the rotator from inside to outside the opening by rotation, the sealing assembly comprising: a seal to slidably contact a surface of an end of the rotator in an axial direction of the rotator, wherein the seal 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, and the seal 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, wherein each of the upstream end and the downstream end in the circumferential direction of the seal is fixed to the bearing surface, and wherein the seal has an unfixed portion in an outer surface of the intermediate portion.
