Abstract:
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.
