  • Grounding plate assembly for a drum in an image forming apparatus
    Patent number: 7020410
    Abstract: A photosensitive drum assembly for an image forming apparatus. A drum defines first and second open ends. A flange is partially disposed in the first open end. A grounding plate assembly includes a drum contact member and a shaft contact member. The drum contact member is configured to remove an electrically resistive coating from an interior of the drum. The shaft contact member is configured to contact a grounding shaft. The shaft contact member is disposed entirely within an interior of the flange.

  • Coupling arrangement including optical photoconductive drum and grounding plate
    Patent number: 6771915
    Abstract: A coupling arrangement with an optical photoconductive drum including a drum interior surface having an electrically resistive coating surrounding and extending along a longitudinal axis. The drum interior surface includes first and second open ends. A flange including a flange interior surface is disposed in the first open end. A flange exterior surface is disposed outside of the first open end. A flange side surface connects the flange interior and exterior surface. A grounding plate is disposed in the first open end and includes an outwardly extending contact that contacts the drum interior surface and removes a portion of the electrically resistive coating to achieve electrical connection with the drum interior surface and to hold the flange.
