ABSTRACT:
An improved gasket device for a bushing which drives a stir-rod has been developed for use in a toner hopper. In one embodiment, the improved gasket uses a crush-resistant material, such as velvet or felt, laminated on a resilient material such as foam tape. The crush-resistant material prevents permanent reduction in the thickness of the gasket by absorbing compressive forces. In a second embodiment, an incompressible shim, for example a steel or plastic shim spaces the felt gasket from the part of the bushing extending from the toner hopper. This tightens the attachment of the bushing to the toner hopper and keeps the felt gasket firmly against the wall of the toner hopper.
