ABSTRACT:
A sealing device is provided for sealing the gap between a rotatable photosensitive member and the housing of a cleaning or developing unit. The sealing device is a membrane sealing member attached at one end to the housing. The other end of the sealing member resiliently contacts the periphery of the photosensitive member when the photosensitive member is at rest. The sealing member has a relatively shallow angle of contact measured from a line parallel to the tangent to the periphery of the photosensitive member and is sufficiently flexible that air entrained by the rotation of the photosensitive member causes the sealing member to be floated from the surface of the photosensitive member.
