Abstract
The present invention relates to seals which may be used in an image forming apparatus. The seals may prevent the leakage of image forming materials, e.g. as between a blade or a roll and an image forming apparatus housing.
Claims24
A sealing member for sealing between printer components comprising:
- a first surface to be engaged with one of said components with a contact pressure wherein said first surface includes one or a plurality of grooves;
- a second surface capable of biasing said first surface to engage with said component wherein said biasing is capable of providing a substantially uniform contact pressure between said first surface and said component
- wherein said second surface capable of biasing said first surface comprises a pair of projecting ribs which define an angle between said projecting ribs of about 1-179 degrees.
A sealing member for sealing between printer components comprising:
- a first surface to be engaged with one of said components wherein said first surface includes one or a plurality of grooves;
- a second surface capable of biasing said first surface to frictionally engage with said component and developing a temperature wherein said temperature between said first surface of said seal and said component is substantially uniform
- wherein said second surface capable of biasing said first surface comprises a pair of projecting ribs which define an angle between said projecting ribs of about 1-179 degrees.
A sealing member for sealing between a developer roller and other printer cartridge components, comprising:
- a first surface capable of engaging with a surface of said developer roller wherein said first surface includes one or a plurality of grooves, said grooves having a substantially vertical wall component of between about 75 degrees to about 105 degrees and a non-vertical wall component intersecting said substantially vertical wall component;
- and
- a second surface capable of biasing said first surface to engage with said developer roll wherein said biasing is capable of providing a substantially uniform contact pressure between said first surface and said developer roil wherein said second surface capable of biasing said first surface comprises a pair of projecting ribs which define an angle between said projecting ribs of about 1-179 degrees.
A sealing member for sealing between a developer roller and a printer cartridge housing comprising:
- a first surface capable of engaging with a surface of said developer roller wherein said first surface includes one or a plurality of grooves wherein said developer roller has an end and said grooves are capable of directing image forming media away from the end of said developer roller when in use;
- and
- a second surface capable of biasing said first surface to engage with said developer roll wherein said biasing is capable of providing a substantially uniform contact pressure between said first surface and said developer roll wherein said second surface capable of biasing said first surface comprises a pair of projecting ribs which define an angle between said projecting ribs of about 1-179 degrees and sealingly engage said printer cartridge housing.
